Granite is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granites can be white, pink, or gray in color. The word granite comes from the Latin granum, a grain, in reference to the structure of such a holocrystalline rock. By definition, granite is a rock with at least 20% quartz. The term granitic means granite-like and is applied to granite and a group of igneous rocks with similar textures and slight variations in composition. Occasionally some individual crystals are larger than the groundmass, in case the texture is known as porphyritic. A granitic rock with a texture is known as a granite porphyry. Granitoid is a general, descriptive field term for lighter-colored, coarse-grained igneous rocks, petrographic examination is required for identification of specific types of granitoids. The extrusive igneous rock equivalent of granite is rhyolite, Granite is nearly always massive and tough, and therefore it has gained widespread use throughout human history, and more recently as a construction stone.
The average density of granite is between 2.65 and 2.75 g/cm3, its compressive strength usually lies above 200 MPa, and its viscosity near STP is 3–6 •1019 Pa·s. The melting temperature of dry granite at ambient pressure is 1215–1260 °C, it is reduced in the presence of water. Granite has poor primary permeability, but strong secondary permeability, true granite according to modern petrologic convention contains both plagioclase and alkali feldspars. When a granitoid is devoid or nearly devoid of plagioclase, the rock is referred to as alkali feldspar granite, when a granitoid contains less than 10% orthoclase, it is called tonalite and amphibole are common in tonalite. A granite containing both muscovite and biotite micas is called a binary or two-mica granite, two-mica granites are typically high in potassium and low in plagioclase, and are usually S-type granites or A-type granites. A worldwide average of the composition of granite, by weight percent, based on 2485 analyses. Much of it was intruded during the Precambrian age, it is the most abundant basement rock that underlies the relatively thin veneer of the continents.
Outcrops of granite tend to form tors and rounded massifs, granites sometimes occur in circular depressions surrounded by a range of hills, formed by the metamorphic aureole or hornfels. Granite often occurs as small, less than 100 km² stock masses
Madrid is the capital city of the Kingdom of Spain and the largest municipality in both the Community of Madrid and Spain as a whole. The city has a population of almost 3.2 million with an area population of approximately 6.5 million. It is the third-largest city in the European Union after London and Berlin, the municipality itself covers an area of 604.3 km2. Madrid lies on the River Manzanares in the centre of both the country and the Community of Madrid, this community is bordered by the communities of Castile and León. As the capital city of Spain, seat of government, and residence of the Spanish monarch, Madrid is the political, the current mayor is Manuela Carmena from Ahora Madrid. Madrid is home to two football clubs, Real Madrid and Atlético de Madrid. Madrid is the 17th most liveable city in the according to Monocle magazine. Madrid organises fairs such as FITUR, ARCO, SIMO TCI, while Madrid possesses modern infrastructure, it has preserved the look and feel of many of its historic neighbourhoods and streets.
Cibeles Palace and Fountain have become one of the monument symbols of the city, the first documented reference of the city originates in Andalusan times as the Arabic مجريط Majrīṭ, which was retained in Medieval Spanish as Magerit. A wider number of theories have been formulated on possible earlier origins, according to legend, Madrid was founded by Ocno Bianor and was named Metragirta or Mantua Carpetana. The most ancient recorded name of the city Magerit comes from the name of a built on the Manzanares River in the 9th century AD. Nevertheless, it is speculated that the origin of the current name of the city comes from the 2nd century BC. The Roman Empire established a settlement on the banks of the Manzanares river, the name of this first village was Matrice. In the 8th century, the Islamic conquest of the Iberian Peninsula saw the changed to Mayrit, from the Arabic term ميرا Mayra. The modern Madrid evolved from the Mozarabic Matrit, which is still in the Madrilenian gentilic, after the disintegration of the Caliphate of Córdoba, Madrid was integrated in the Taifa of Toledo.
With the surrender of Toledo to Alfonso VI of León and Castile, the city was conquered by Christians in 1085, Christians replaced Muslims in the occupation of the centre of the city, while Muslims and Jews settled in the suburbs. The city was thriving and was given the title of Villa, since 1188, Madrid won the right to be a city with representation in the courts of Castile. In 1202, King Alfonso VIII of Castile gave Madrid its first charter to regulate the municipal council, which was expanded in 1222 by Ferdinand III of Castile
By population, Spain is the sixth largest in Europe and the fifth in the European Union. Spains capital and largest city is Madrid, other urban areas include Barcelona, Seville, Bilbao. Modern humans first arrived in the Iberian Peninsula around 35,000 years ago, in the Middle Ages, the area was conquered by Germanic tribes and by the Moors. Spain is a democracy organised in the form of a government under a constitutional monarchy. It is a power and a major developed country with the worlds fourteenth largest economy by nominal GDP. Jesús Luis Cunchillos argues that the root of the span is the Phoenician word spy. Therefore, i-spn-ya would mean the land where metals are forged, two 15th-century Spanish Jewish scholars, Don Isaac Abravanel and Solomon ibn Verga, gave an explanation now considered folkloric. Both men wrote in two different published works that the first Jews to reach Spain were brought by ship by Phiros who was confederate with the king of Babylon when he laid siege to Jerusalem.
This man was a Grecian by birth, but who had given a kingdom in Spain. He became related by marriage to Espan, the nephew of king Heracles, Heracles renounced his throne in preference for his native Greece, leaving his kingdom to his nephew, from whom the country of España took its name. Based upon their testimonies, this eponym would have already been in use in Spain by c.350 BCE, Iberia enters written records as a land populated largely by the Iberians and Celts. Early on its coastal areas were settled by Phoenicians who founded Western Europe´s most ancient cities Cadiz, Phoenician influence expanded as much of the Peninsula was eventually incorporated into the Carthaginian Empire, becoming a major theater of the Punic Wars against the expanding Roman Empire. After an arduous conquest, the peninsula came fully under Roman Rule, during the early Middle Ages it came under Germanic rule but later, much of it was conquered by Moorish invaders from North Africa. In a process took centuries, the small Christian kingdoms in the north gradually regained control of the peninsula.
The last Moorish kingdom fell in the same year Columbus reached the Americas, a global empire began which saw Spain become the strongest kingdom in Europe, the leading world power for a century and a half, and the largest overseas empire for three centuries. Continued wars and other problems led to a diminished status. The Napoleonic invasions of Spain led to chaos, triggering independence movements that tore apart most of the empire, eventually democracy was peacefully restored in the form of a parliamentary constitutional monarchy. Spain joined the European Union, experiencing a renaissance and steady economic growth
Juan de Herrera
Juan de Herrera was a Spanish architect and geometrician. One of the most outstanding Spanish architects in the 16th century and his sober style was fully developed in buildings like the Monastery of San Lorenzo de El Escorial. The Herrerian style was named after him, and was representative of the architecture of the Spanish Empire of Philip II, as a Renaissance man, Herrera was interested in all the branches of knowledge of his times. His Discurso sobre la figura cúbica tells us about his knowledge about geometry. He participated in the campaigns of Charles V in Germany, Flanders. Juan de Herrera completed his studies at the University of Valladolid in the spring of 1548 and he started his architectural career in 1561 with the works in the Royal Palace of Aranjuez, following it in 1562 with Libro del saber de astronomía. In 1563 he started to work under Juan Bautista de Toledo in the construction of El Escorial, stylistically, he changed the image of the façades and introducing his personal sober style.
The main keys of his design are the impressive horizontal unified composition and this style introduced in the monastery influenced Spanish architecture for over a century with the name of Herrerian style. The plans of the Cathedral of Valladolid and the Archivo General de Indias were designed by him and he was the original designer for the Plaza Mayor in Madrid. As instructed in his 1584 will, his sepulchre is located in the Church of San Juan Bautista, in Maliaño, one of the gates of the Walls of Seville.

Philip II of Spain
Philip II of Spain, called the Prudent, was King of Spain, King of Portugal, King of Naples and Sicily, and jure uxoris King of England and Ireland. He was Duke of Milan, from 1555, he was lord of the Seventeen Provinces of the Netherlands. Known in Spain as Felipe el Prudente, his empire included territories on every continent known to Europeans, during his reign, Spain reached the height of its influence and power. This is sometimes called the Golden Age, the expression, the empire on which the sun never sets, was coined during Philips time to reflect the extent of his dominion. During Philips reign there were separate state bankruptcies in 1557,1560,1569,1575 and this was partly the cause of the declaration of independence that created the Dutch Republic in 1581. The Ambassador went on to say He dresses very tastefully, the culture and courtly life of Spain were an important influence in his early life. He was tutored by Juan Martínez Siliceo, the future Archbishop of Toledo, Philip displayed reasonable aptitude in arms and letters alike.
Later he would study with more illustrious tutors, including the humanist Juan Cristóbal Calvete de Estrella, though Philip had good command over Latin and Portuguese, he never managed to equal his father, Charles V, as a polyglot. While Philip was a German archduke of the House of Habsburg, Philip felt himself to be culturally Spanish, he had been born in Spain and raised in the Castilian court, his native tongue was Spanish, and he preferred to live in Spain. This would ultimately impede his succession to the imperial throne, in April 1528, when Philip was eleven months old, he received the oath of allegiance as heir to the crown from the Cortes of Castile. Philip was close to his two sisters, María and Juana, and to his two pages, the Portuguese nobleman Rui Gomes da Silva and Luis de Requesens, the son of his governor Juan de Zúñiga. These men would serve Philip throughout their lives, as would Antonio Pérez, Philips martial training was undertaken by his governor, Juan de Zúñiga, a Castilian nobleman who served as the commendador mayor of Castile.
The practical lessons in warfare were overseen by the Duke of Alba during the Italian Wars, Philip was present at the Siege of Perpignan in 1542 but did not see action as the Spanish army under Alba decisively defeated the besieging French forces under the Dauphin of France. On his way back to Castile, Philip received the oath of allegiance of the Aragonese Cortes at Monzón. The king-emperors interactions with his son during his stay in Spain convinced him of Philips precocity in statesmanship, who had previously been made the Duke of Milan in 1540, began governing the most extensive empire in the world at the young age of sixteen. Charles left Philip with experienced advisors—notably the secretary Francisco de los Cobos, Philip was left with extensive written instructions that emphasised piety, patience and distrust. These principles of Charles were gradually assimilated by his son, who would grow up to become grave, self-possessed, Philip spoke softly and had an icy self-mastery, in the words of one of his ministers, he had a smile that cut like a sword.
After living in the Netherlands in the years of his reign
The Manzanares is a river in central Spain, which flows from the Sierra de Guadarrama, passes through Madrid, and eventually empties into the Jarama river, which in turn is a tributary to the Tagus. The river Manzanares has its source near the Navacerrada mountain pass in the Guadarrama mountain range, the upper river basin is protected as the Parque Regional de la Cuenca Alta del Manzanares, a nature reserve which is recognised as a biosphere reserve by UNESCO. The river takes a southern direction and enters the Monte del Pardo, the river is canalised where it passes through the built-up areas of the city. As at 2009 a project is in progress to provide river beaches and it is along this stretch that it passes next to Atlético Madrids football ground, the Vicente Calderón. The river leaves the city at its southernmost tip, the river Manzanares, although small and relatively unimportant geographically, has had a great historical importance due to its close relation to the city of Madrid. The city was founded by the Moors as a citadel overlooking the river in the ninth century, the Bridge of the French was of crucial importance because of its strategic location.
There, nationalists forces were repelled and denied access to Madrid’s city center
