The police are a constituted body of persons empowered by a state to enforce the law, to protect the lives and possessions of citizens, to prevent crime and civil disorder. Their powers include the legitimized use of force; the term is most associated with the police forces of a sovereign state that are authorized to exercise the police power of that state within a defined legal or territorial area of responsibility. Police forces are defined as being separate from the military and other organizations involved in the defense of the state against foreign aggressors. Police forces are public sector services, funded through taxes. Law enforcement is only part of policing activity. Policing has included an array of activities in different situations, but the predominant ones are concerned with the preservation of order. In some societies, in the late 18th and early 19th centuries, these developed within the context of maintaining the class system and the protection of private property. Police forces have become ubiquitous in modern societies.
Their role can be controversial, as some are involved to varying degrees in corruption, police brutality and the enforcement of authoritarian rule. A police force may be referred to as a police department, police service, gendarmerie, crime prevention, protective services, law enforcement agency, civil guard or civic guard. Members may be referred to as police officers, sheriffs, rangers, peace officers or civic/civil guards. Ireland differs from other English-speaking countries by using the Irish language terms Garda and Gardaí, for both the national police force and its members; the word police is the most universal and similar terms can be seen in many non-English speaking countries. Numerous slang terms exist for the police. Many slang terms for police officers are centuries old with lost etymology. One of the oldest, "cop", has lost its slang connotations and become a common colloquial term used both by the public and police officers to refer to their profession. First attested in English in the early 15th century in a range of senses encompassing' policy.
This is derived from πόλις, "city". Law enforcement in ancient China was carried out by "prefects" for thousands of years since it developed in both the Chu and Jin kingdoms of the Spring and Autumn period. In Jin, dozens of prefects were spread across the state, each having limited authority and employment period, they were appointed by local magistrates, who reported to higher authorities such as governors, who in turn were appointed by the emperor, they oversaw the civil administration of their "prefecture", or jurisdiction. Under each prefect were "subprefects" who helped collectively with law enforcement in the area; some prefects were responsible for handling investigations, much like modern police detectives. Prefects could be women; the concept of the "prefecture system" spread to other cultures such as Japan. In ancient Greece, publicly owned slaves were used by magistrates as police. In Athens, a group of 300 Scythian slaves was used to guard public meetings to keep order and for crowd control, assisted with dealing with criminals, handling prisoners, making arrests.
Other duties associated with modern policing, such as investigating crimes, were left to the citizens themselves. In the Roman empire, the army, rather than a dedicated police organization, provided security. Local watchmen were hired by cities to provide some extra security. Magistrates such as procurators fiscal and quaestors investigated crimes. There was no concept of public prosecution, so victims of crime or their families had to organize and manage the prosecution themselves. Under the reign of Augustus, when the capital had grown to one million inhabitants, 14 wards were created, their duties included capturing runaway slaves. The vigiles were supported by the Urban Cohorts who acted as a heavy-duty anti-riot force and the Praetorian Guard if necessary. In medieval Spain, Santa Hermandades, or "holy brotherhoods", peacekeeping associations of armed individuals, were a characteristic of municipal life in Castile; as medieval Spanish kings could not offer adequate protection, protective municipal leagues began to emerge in the twelfth century against banditry and other rural criminals, against the lawless nobility or to support one or another claimant to a crown.
These organizations became a long-standing fixture of Spain. The first recorded case of the formation of an hermandad occurred when the towns and the peasantry of the north united to police the pilgrim road to Santiago de Compostela in Galicia, protect the pilgrims against robber knights. Throughout the Middle Ages such alliances were formed by combinations of towns to protect the roads connecting them, were extended to political purposes. Among the most powerful was the league of North Castilian and Basque ports, the Hermandad de las marismas: Toledo and Villarreal; as one of their first acts after end of the War of the Castilian Succession in 1479, Ferdinand II of Aragon and Isabella I of Castile established the centrally-organized and efficient Holy
Cairo is the capital of Egypt. The city's metropolitan area is one of the largest in Africa, the largest in the Middle East, the 15th-largest in the world, is associated with ancient Egypt, as the famous Giza pyramid complex and the ancient city of Memphis are located in its geographical area. Located near the Nile Delta, modern Cairo was founded in 969 CE by the Fatimid dynasty, but the land composing the present-day city was the site of ancient national capitals whose remnants remain visible in parts of Old Cairo. Cairo has long been a centre of the region's political and cultural life, is titled "the city of a thousand minarets" for its preponderance of Islamic architecture. Cairo is considered a World City with a "Beta +" classification according to GaWC. Cairo has the oldest and largest film and music industries in the Middle East, as well as the world's second-oldest institution of higher learning, Al-Azhar University. Many international media and organizations have regional headquarters in the city.
With a population of over 9 million spread over 3,085 square kilometers, Cairo is by far the largest city in Egypt. An additional 9.5 million inhabitants live in close proximity to the city. Cairo, like many other megacities, suffers from high levels of traffic. Cairo's metro, one of two in Africa, ranks among the fifteen busiest in the world, with over 1 billion annual passenger rides; the economy of Cairo was ranked first in the Middle East in 2005, 43rd globally on Foreign Policy's 2010 Global Cities Index. Egyptians refer to Cairo as Maṣr, the Egyptian Arabic name for Egypt itself, emphasizing the city's importance for the country, its official name al-Qāhirah means "the Vanquisher" or "the Conqueror" due to the fact that the planet Mars, an-Najm al-Qāhir, was rising at the time when the city was founded also in reference to the much awaited arrival of the Fatimid Caliph Al-Mu'izz who reached Cairo in 973 from Mahdia, the old Fatimid capital. The location of the ancient city of Heliopolis is the suburb of Ain Shams.
The Coptic name of the city is Kashromi which means "man breaker", akin to Arabic al-Qāhirah . Sometimes the city is informally referred to as Kayro by people from Alexandria; the area around present-day Cairo Memphis, the old capital of Egypt, had long been a focal point of Ancient Egypt due to its strategic location just upstream from the Nile Delta. However, the origins of the modern city are traced back to a series of settlements in the first millennium. Around the turn of the 4th century, as Memphis was continuing to decline in importance, the Romans established a fortress town along the east bank of the Nile; this fortress, known as Babylon, was the nucleus of the Roman and the Byzantine city and is the oldest structure in the city today. It is situated at the nucleus of the Coptic Orthodox community, which separated from the Roman and Byzantine churches in the late 4th century. Many of Cairo's oldest Coptic churches, including the Hanging Church, are located along the fortress walls in a section of the city known as Coptic Cairo.
Following the Muslim conquest in 640 AD, the conqueror Amr ibn As settled to the north of the Babylon in an area that became known as al-Fustat. A tented camp Fustat became a permanent settlement and the first capital of Islamic Egypt. In 750, following the overthrow of the Umayyad caliphate by the Abbasids, the new rulers created their own settlement to the northeast of Fustat which became their capital; this was known as al-Askar. A rebellion in 869 by Ahmad ibn Tulun led to the abandonment of Al Askar and the building of another settlement, which became the seat of government; this was al-Qatta ` closer to the river. Al Qatta'i was centred around a ceremonial mosque, now known as the Mosque of ibn Tulun. In 905, the Abbasids re-asserted control of the country and their governor returned to Fustat, razing al-Qatta'i to the ground. Since 1860s, Cairo expanded west as far as what is called now In 968, the Fatimids were led by general Jawhar al-Siqilli to establish a new capital for the Fatimid dynasty.
Egypt was conquered from their base in Ifriqiya and a new fortified city northeast of Fustat was established. It took four years to build the city known as al-Manṣūriyyah, to serve as the new capital of the caliphate. During that time, Jawhar commissioned the construction of the al-Azhar Mosque by order of the Caliph, which developed into the third-oldest university in the world. Cairo would become a centre of learning, with the library of Cairo containing hundreds of thousands of books; when Caliph al-Mu'izz li Din Allah arrived from the old Fatimid capital of Mahdia in Tunisia in 973, he gave the city its present name, al-Qāhiratu. For nearly 200 years after Cairo was established, the administrative centre of Egypt remained in Fustat. However, in 1168 the Fatimids under the leadership of vizier Shawar set fire to Fustat to prevent Cairo's capture by the Crusaders. Egypt's capital was permanently moved to Cairo, expanded to include the ruins of Fustat and the previous capitals of
Valley of the Kings
The Valley of the Kings known as the Valley of the Gates of the Kings, is a valley in Egypt where, for a period of nearly 500 years from the 16th to 11th century BC, rock cut tombs were excavated for the pharaohs and powerful nobles of the New Kingdom. The valley stands on the west bank of the Nile, opposite Thebes, within the heart of the Theban Necropolis; the wadi consists of East Valley and West Valley. With the 2005 discovery of a new chamber and the 2008 discovery of two further tomb entrances, the valley is known to contain 63 tombs and chambers, it was the principal burial place of the major royal figures of the Egyptian New Kingdom, as well as a number of privileged nobles. The royal tombs are decorated with scenes from Egyptian mythology and give clues as to the beliefs and funerary rituals of the period. All of the tombs seem to have been opened and robbed in antiquity, but they still give an idea of the opulence and power of the pharaohs; this area has been a focus of archaeological and egyptological exploration since the end of the eighteenth century, its tombs and burials continue to stimulate research and interest.
In modern times the valley has become famous for the discovery of the tomb of Tutankhamun, is one of the most famous archaeological sites in the world. In 1979, it became a World Heritage Site, along with the rest of the Theban Necropolis. Exploration and conservation continues in the valley, a new tourist centre has been opened; the Valley of the Kings is situated over 1,000 feet of limestone and other sedimentary rock, which form the cliffs in the valley and the nearby Deir el-Bahri, interspersed with soft layers of marl. The sedimentary rock was deposited between 35–56 million years ago during a time when the Mediterranean Sea sometimes extended as far south as Aswan. During the Pleistocene the valley was carved out of the plateau by steady rains. There is little year-round rain in this part of Egypt, but there are occasional flash floods that hit the valley, dumping tons of debris into the open tombs; the quality of the rock in the Valley is inconsistent, ranging from finely-grained to coarse stone, the latter with the potential to be structurally unsound.
The occasional layer of shale caused construction and conservation difficulties, as this rock expands in the presence of water, forcing apart the stone surrounding it. It is thought that some tombs were altered in shape and size depending on the types of rock the builders encountered. Builders took advantage of available geological features; some tombs were quarried out of existing limestone clefts, others behind slopes of scree, or were at the edge of rock spurs created by ancient flood channels. The problems of tomb construction can be seen with tombs of his father Setnakhte. Setnakhte started to excavate KV11 but broke into the tomb of Amenmesse, so construction was abandoned and he instead usurped the tomb of Twosret, KV14; when looking for a tomb, Ramesses III extended. The tomb of Ramesses II returned to an early style, with a bent axis due to the quality of the rock being excavated. Between 1998 and 2002 the Amarna Royal Tombs Project investigated the valley floor using ground-penetrating radar and found that, below the modern surface, the Valley's cliffs descend beneath the scree in a series of abrupt, natural "shelves", arranged one below the other, descending several metres down to the bedrock in the valley floor.
The area of the Theban hills is subject to infrequent violent thunderstorms, causing flash floods in the valley. Recent studies have shown that there are at least seven active flood stream beds leading down into the central area of the valley; this central area appears to have been flooded at the end of the Eighteenth Dynasty, with several tombs buried under metres of debris. The tombs KV63, KV62, KV55 are dug into the actual wadi bedrock rather than the debris, showing that the level of the valley was five meters below its present level. After this event dynasties leveled the floor of the valley, making the floods deposit their load further down the valley, the buried tombs were forgotten and only discovered in the early 20th century; this was the area, the subject of the Amarna Royal Tombs Project ground scanning radar investigation, which showed several anomalies, one of, proved to be KV63. The Theban Hills are dominated by the peak of al-Qurn, known to the Ancient Egyptians as ta dehent, or "The Peak".
It has a pyramid-shaped appearance, it is probable that this echoed the pyramids of the Old Kingdom, more than a thousand years prior to the first royal burials carved here. Its isolated position resulted in reduced access, special tomb police were able to guard the necropolis. While the iconic pyramid complexes of the Giza plateau have come to symbolize ancient Egypt, the majority of tombs were cut into rock. Most pyramids and mastabas contain sections which are cut into ground level, there are full rock-cut tombs in Egypt that date back to the Old Kingdom. After the defeat of the Hyksos and the reunification of Egypt under Ahmose I, the Theban rulers began to construct elaborate tombs that reflected their newfound power; the tombs of Ahmose and his son Amenhotep I were in the Seventeenth Dyna
Iraq the Republic of Iraq, is a country in Western Asia, bordered by Turkey to the north, Iran to the east, Kuwait to the southeast, Saudi Arabia to the south, Jordan to the southwest and Syria to the west. The capital, largest city, is Baghdad. Iraq is home to diverse ethnic groups including Arabs, Assyrians, Shabakis, Armenians, Mandeans and Kawliya. Around 95% of the country's 37 million citizens are Muslims, with Christianity, Yarsan and Mandeanism present; the official languages of Iraq are Kurdish. Iraq has a coastline measuring 58 km on the northern Persian Gulf and encompasses the Mesopotamian Alluvial Plain, the northwestern end of the Zagros mountain range and the eastern part of the Syrian Desert. Two major rivers, the Tigris and Euphrates, run south through Iraq and into the Shatt al-Arab near the Persian Gulf; these rivers provide Iraq with significant amounts of fertile land. The region between the Tigris and Euphrates rivers known as Mesopotamia, is referred to as the cradle of civilisation.
It was here that mankind first began to read, create laws and live in cities under an organised government—notably Uruk, from which "Iraq" is derived. The area has been home to successive civilisations since the 6th millennium BC. Iraq was the centre of the Akkadian, Sumerian and Babylonian empires, it was part of the Median, Hellenistic, Sassanid, Rashidun, Abbasid, Mongol, Safavid and Ottoman empires. The country today known as Iraq was a region of the Ottoman Empire until the partition of the Ottoman Empire in the 20th century, it was made up of three provinces, called vilayets in the Ottoman language: Mosul Vilayet, Baghdad Vilayet, Basra Vilayet. In April 1920 the British Mandate of Mesopotamia was created under the authority of the League of Nations. A British-backed monarchy joining these vilayets into one Kingdom was established in 1921 under Faisal I of Iraq; the Hashemite Kingdom of Iraq gained independence from the UK in 1932. In 1958, the monarchy was overthrown and the Iraqi Republic created.
Iraq was controlled by the Arab Socialist Ba'ath Party from 1968 until 2003. After an invasion by the United States and its allies in 2003, Saddam Hussein's Ba'ath Party was removed from power, multi-party parliamentary elections were held in 2005; the US presence in Iraq ended in 2011, but the Iraqi insurgency continued and intensified as fighters from the Syrian Civil War spilled into the country. Out of the insurgency came a destructive group calling itself ISIL, which took large parts of the north and west, it has since been defeated. Disputes over the sovereignty of Iraqi Kurdistan continue. A referendum about the full sovereignty of Iraqi Kurdistan was held on 25 September 2017. On 9 December 2017, then-Iraqi Prime Minister Haider al-Abadi declared victory over ISIL after the group lost its territory in Iraq. Iraq is a federal parliamentary republic consisting of one autonomous region; the country's official religion is Islam. Culturally, Iraq has a rich heritage and celebrates the achievements of its past in both pre-Islamic as well as post-Islamic times and is known for its poets.
Its painters and sculptors are among the best in the Arab world, some of them being world-class as well as producing fine handicrafts, including rugs and carpets. Iraq is a founding member of the UN as well as of the Arab League, OIC, Non-Aligned Movement and the IMF; the Arabic name العراق al-ʿIrāq has been in use since before the 6th century. There are several suggested origins for the name. One dates to the Sumerian city of Uruk and is thus of Sumerian origin, as Uruk was the Akkadian name for the Sumerian city of Urug, containing the Sumerian word for "city", UR. An Arabic folk etymology for the name is "well-watered. During the medieval period, there was a region called ʿIrāq ʿArabī for Lower Mesopotamia and ʿIrāq ʿAjamī, for the region now situated in Central and Western Iran; the term included the plain south of the Hamrin Mountains and did not include the northernmost and westernmost parts of the modern territory of Iraq. Prior to the middle of the 19th century, the term Eyraca Arabic was used to describe Iraq.
The term Sawad was used in early Islamic times for the region of the alluvial plain of the Tigris and Euphrates rivers, contrasting it with the arid Arabian desert. As an Arabic word, عراق means "hem", "shore", "bank", or "edge", so that the name by folk etymology came to be interpreted as "the escarpment", viz. at the south and east of the Jazira Plateau, which forms the northern and western edge of the "al-Iraq arabi" area. The Arabic pronunciation is. In English, it is either or, the American Heritage Dictionary, the Random House Dictionary; the pronunciation is heard in US media. In accordance with the 2005 Constitution, the official name of the state is the "Republic of Iraq". Between 65,000 BC and 35,000 BC northern Iraq was home to a Neanderthal culture, archaeological remains of which have been discovered at Shanidar Cave This same region is the location of a number of pre-Neolithic cemeteries, dating from 11,000 BC. Since 10,000 BC, Iraq was one of centres of a Caucasoid Neolithic culture (k
The Saladin Citadel of Cairo is a medieval Islamic fortification in Cairo, Egypt. The location, on Mokattam hill near the center of Cairo, was once famous for its fresh breeze and grand views of the city, it is now a preserved historic site, with museums. In 1976, it was proclaimed by UNESCO as a part of the World Heritage Site Historic Cairo, "the new centre of the Islamic world, reaching its golden age in the 14th century." The Citadel was fortified by the Kurdish Ayyubid ruler Salah al-Din between 1176 and 1183 CE, to protect it from the Crusaders. Only a few years after defeating the Fatimid Caliphate, Saladin set out to build a wall that would surround both Cairo and Fustat. Saladin is recorded as saying, "With a wall I will make the two into a unique whole, so that one army may defend them both; the Citadel would be the centerpiece of the wall. Built on a promontory beneath the Muqattam Hills, a setting that made it difficult to attack, the efficacy of the Citadel's location is further demonstrated by the fact that it remained the heart of Egyptian government until the 19th century.
The citadel stopped being the seat of government when Egypt's ruler, Khedive Ismail, moved to his newly built Abdin Palace in the Ismailiya neighborhood in the 1860s. While the Citadel was completed in 1183–1184, the wall Saladin had envisioned was still under construction in 1238, long after his death. To supply water to the Citadel, Saladin built the 85-metre deep Well of Joseph, which can still be seen today; this well is known as the Well of the Spiral because its entrance consisted of 300 stairs that wound around the inside of the well. Once water was raised from the well to the surface, it traveled to the Citadel on a series of aqueducts. During the reign of al-Nasir Muhammad, the Well of Joseph failed to produce enough water for the numerous animals and humans living in the Citadel. To increase the volume of water, Nasir built a well system that consisted of a number of water wheels on the Nile, the water from, transported to the wall and subsequently to the Citadel, via the aqueducts Saladin had constructed.
The improvements to the Citadel's water supply were not Nasir's only additions to the Citadel, subject to a number of different additions during the Mamluk period. Nasir's most notable contribution was the Mosque of Nasir. In 1318 Nasir rebuilt the Ayyubid structure; the structure underwent further additions in 1335. Other contributions to the Citadel during Nasir's reign include the structure's southern enclosure and the residential area, which included space for the harem and the courtyard. Prior to Nasir's work on the Citadel, the Baybars constructed the Hall of Justice and the "House of Gold." The Citadel is sometimes referred to as Mohamed Ali Citadel, because it contains the Mosque of Muhammad Ali, built by Muhammad Ali Pasha between 1828 and 1848, perched on the summit of the citadel. This Ottoman mosque was built in memory of Tusun Pasha, Muhammad Ali's second son who died in 1816. However, it represents Muhammad Ali's efforts to erase symbols of the Mamluk dynasty that he replaced; when Ottoman ruler Muhammad Ali Pasha took control from the Mamluks in 1805 he altered many of the additions to the Citadel that reflected Cairo's previous leaders.
One obvious change that Muhammad Ali enacted pertained to the uses of the Citadel's northern and southern enclosures. During the Mamluk period the southern enclosure was the residential area, but Muhammad Ali claimed the northern enclosure as the royal residence when he took power, he opened the southern enclosure to the public and established his position as the new leader. The mosque is the other feature of the Citadel; this feature, with its large dome and overtly Ottoman influenced architecture, looms over the Citadel to this day. Destroyed Mamluk palaces within the Citadel provided space for the formidable mosque, the largest structure to be established in the early 19th century. Placing the mosque where the Mamluks had once reigned was an obvious effort to erase the memory of the older rulers and establish the importance of the new leader; the mosque replaced the mosque of al-Nasir as the official state mosque. There are three main mosques at the Citadel: Mosque of Muhammad AliThe mosque was built between 1830 and 1848, although not completed until the reign of Said Pasha in 1857.
The architect was Yusuf Bushnak from Istanbul and its model was the Sultan Ahmed Mosque in that city. Muhammad Ali Pasha was buried in a tomb carved in the courtyard of the mosque, his body was transferred here from Hawsh al-Basha in 1857. Al-Nasir Muhammad MosqueBuilt in 1318, during the early Bahri Mamluk period, as the royal mosque of the Citadel where the sultans of Cairo performed their Friday prayers, today this hypostyle mosque is still similar to how it looked in the 1300 though many repairs have been made, it is open to the public. The parts of the building relying on plastered walls have been reinforced. There have been attempts to restore the light-blue color of the ceiling. Mosque of Sulayman PashaBuilt in 1528, it was first of the Citadel's Ottoman-style mosques, it was built on the ruins of an old mosque of Abu Mansur Qusta. The Citadel contains museums: Al-Gawhara Palace MuseumAlso known as Bi
Architecture is both the process and the product of planning and constructing buildings or any other structures. Architectural works, in the material form of buildings, are perceived as cultural symbols and as works of art. Historical civilizations are identified with their surviving architectural achievements. Architecture is both the process and the product of planning and constructing buildings and other physical structures. Architecture can mean: A general term to describe other physical structures; the art and science of designing buildings and nonbuilding structures. The style of design and method of construction of buildings and other physical structures. A unifying or coherent form or structure. Knowledge of art, science and humanity; the design activity of the architect, from the macro-level to the micro-level. The practice of the architect, where architecture means offering or rendering professional services in connection with the design and construction of buildings, or built environments.
The earliest surviving written work on the subject of architecture is De architectura, by the Roman architect Vitruvius in the early 1st century AD. According to Vitruvius, a good building should satisfy the three principles of firmitas, venustas known by the original translation – firmness and delight. An equivalent in modern English would be: Durability – a building should stand up robustly and remain in good condition. Utility – it should be suitable for the purposes for which it is used. Beauty – it should be aesthetically pleasing. According to Vitruvius, the architect should strive to fulfill each of these three attributes as well as possible. Leon Battista Alberti, who elaborates on the ideas of Vitruvius in his treatise, De Re Aedificatoria, saw beauty as a matter of proportion, although ornament played a part. For Alberti, the rules of proportion were those that governed the idealised human figure, the Golden mean; the most important aspect of beauty was, therefore, an inherent part of an object, rather than something applied superficially, was based on universal, recognisable truths.
The notion of style in the arts was not developed until the 16th century, with the writing of Vasari: by the 18th century, his Lives of the Most Excellent Painters and Architects had been translated into Italian, French and English. In the early 19th century, Augustus Welby Northmore Pugin wrote Contrasts that, as the titled suggested, contrasted the modern, industrial world, which he disparaged, with an idealized image of neo-medieval world. Gothic architecture, Pugin believed, was the only "true Christian form of architecture." The 19th-century English art critic, John Ruskin, in his Seven Lamps of Architecture, published 1849, was much narrower in his view of what constituted architecture. Architecture was the "art which so disposes and adorns the edifices raised by men... that the sight of them" contributes "to his mental health and pleasure". For Ruskin, the aesthetic was of overriding significance, his work goes on to state that a building is not a work of architecture unless it is in some way "adorned".
For Ruskin, a well-constructed, well-proportioned, functional building needed string courses or rustication, at the least. On the difference between the ideals of architecture and mere construction, the renowned 20th-century architect Le Corbusier wrote: "You employ stone and concrete, with these materials you build houses and palaces:, construction. Ingenuity is at work, but you touch my heart, you do me good. I am happy and I say: This is beautiful; that is Architecture". Le Corbusier's contemporary Ludwig Mies van der Rohe said "Architecture starts when you put two bricks together. There it begins." The notable 19th-century architect of skyscrapers, Louis Sullivan, promoted an overriding precept to architectural design: "Form follows function". While the notion that structural and aesthetic considerations should be subject to functionality was met with both popularity and skepticism, it had the effect of introducing the concept of "function" in place of Vitruvius' "utility". "Function" came to be seen as encompassing all criteria of the use and enjoyment of a building, not only practical but aesthetic and cultural.
Nunzia Rondanini stated, "Through its aesthetic dimension architecture goes beyond the functional aspects that it has in common with other human sciences. Through its own particular way of expressing values, architecture can stimulate and influence social life without presuming that, in and of itself, it will promote social development.' To restrict the meaning of formalism to art for art's sake is not only reactionary. Among the philosophies that have influenced modern architects and their approach to building design are rationalism, structuralism, poststructuralism, phenomenology. In the late 20th century a new concept was added to those included in the compass of both structure and function, the consideration of sustainability, hence sustainable architecture. To satisfy the contemporary ethos a building should be constructed in a manner, environmentally friendly in terms of the production of its materials, its impact upon the natural and built environment of its surrounding area and the demands that it makes upon non-sustainable power sources for heating, cooling and waste management and lighting
