National Library of Scotland

The National Library of Scotland is the legal deposit library of Scotland and is one of the country's National Collections. Its main public building is in Edinburgh city centre on George IV Bridge, between the Old Town and the university quarter; this building is Category A listed. There is a more modern building in a residential area on the south side of the town centre, on Causewayside; this was built to accommodate some of the specialist collections, such as maps and science collections, to provide extra large-scale storage. In 2016 a new public centre opened at Glasgow's Kelvin Hall providing access to the Library's digital and moving image collections; the National Library of Scotland holds 7 million books, 14 million printed items and over 2 million maps. The collection includes copies of the Gutenberg Bible, the letter which Charles Darwin submitted with the manuscript of Origin of Species, the First Folio of Shakespeare, the Glenriddell Manuscripts and numerous journals and other publications.

It has the largest collection of Scottish Gaelic material of any library. Scotland's national deposit library was the Advocates Library belonging to the Faculty of Advocates, it was opened in 1689 and gained national library status in the 1710 Copyright Act, giving it the legal right to a copy of every book published in Great Britain. In the following centuries, the library added books and manuscripts to the collections by purchase as well as legal deposit, creating a funded national library in all but name. By the 1920s, the upkeep of such a major collection was too much for a private body, with an endowment of £100,000 provided by Alexander Grant, managing director of McVitie & Price, the Library's contents were presented to the nation; the National Library of Scotland was formally constituted by Act of Parliament in 1925. Grant's support was recognised with a baronetcy, in June 1924 he became Sir Alexander Grant of Forres. In 1928 he donated a further £100,000 – making his combined donations the equivalent of around £6 million today – for a new library building to be constructed on George IV Bridge, replacing the Victorian-period Sheriff Court, which institution moved to the Royal Mile.

Government funding was secured. Work on the new building was started in 1938, interrupted by the Second World War, completed in 1956; the architect was Reginald Fairlie. The coat of arms above the entrance was sculpted by Scott Sutherland and the roundels above the muses on the front facade by Elizabeth Dempster. By the 1970s, room for the ever-expanding collections was running out, other premises were needed; the Causewayside Building opened in the south-side of Edinburgh in two phases, in 1989 and in 1995, at a total cost of £50 million, providing much-needed additional working space and storage facilities. Since 1999, the Library has been funded by the Scottish Parliament, it remains one of only six legal deposit libraries in the United Kingdom and Ireland, is governed by a board of trustees. The Library holds many ancient family manuscripts including those of the Clan Sinclair, which date back as far as 1488. On 26 February 2009, areas of the building were flooded after a water main burst on the 12th floor.

Firefighters were called and the leaking water was stopped within ten minutes. A number of items were damaged; the last letter written by Mary Queen of Scots made a rare public appearance to mark the opening of a new Library visitor centre in September 2009. The Library joined the 10:10 project in 2010 in a bid to reduce their carbon footprint. One year they announced that they had reduced their carbon emissions according to 10:10's criteria by 18%. On 16 May 2012 the National Library of Scotland Act 2012 was passed by the Scottish Parliament, received Royal Assent in 21 June 2012. In April 2013 the Library advertised for a Wikipedian in residence, becoming the first institution in the Scotland to create such a post. In 2016, the Library recruited a Gaelic Wikipedian in residence. In September 2016 the Library opened a new centre at the refurbished Kelvin Hall, Glasgow, in partnership with Glasgow Life and the University of Glasgow; the centre provides access to moving image collections. As of 2013, the Library holds: manuscripts: 100,000 items maps: 2 million items films: more than 46,000 items newspaper and magazine titles: 25,000 items Bartholomew Archive John Murray Archive Scottish Publishers Association Ask Scotland, Scotland's online information service provided by Scotland’s libraries Books in the United Kingdom Official website

Vilnius TV Tower

The Vilnius TV Tower is a 326.5 m high tower in the Karoliniškės microdistrict of Vilnius, Lithuania. It is the tallest structure in Lithuania, is occupied by the SC Lithuanian Radio and Television Centre; the tower was designed by the engineering section by K. Balėnas; the construction of the tower started on 31 May 1974 and finished on December 30, 1980. The construction was funded by the 11th Five Year Plan of the Soviet Union, which had earmarked funds for strategic investment in the Lithuanian SSR; the weight of the whole structure is estimated at 25,000 to 30,000 metric tons. The structure is composed of a concrete base, a 190 m long hollow reinforced concrete pipe, a reinforced concrete saucer, a 136 m long steel spike. Radio transmitters are housed in the lower part of the concrete tower with antennas attached to the steel spike; the observation deck 165 m from the ground houses the cafe "Paukščių takas", offers a picturesque view of the city and its surroundings, sports a rotating platform that revolves once every 45 minutes.

High-speed elevators reach the cafe from ground level in 40 seconds. On clear days, visibility can extend as far as Elektrėnai, a city 40 km west, where power plants produced much of the electricity for Vilnius in Soviet times; the TV tower played a major role in the events of 13 January 1991, when 14 unarmed civilians lost their lives and 700 were injured opposing the Soviet military seizure of the tower. A small museum dedicated to the January 1991 battle is housed on the ground floor, various markers in the surrounding area indicate places where Lithuanian citizens died while trying to maintain the blockade against Soviet troops. Since 2000, the tower has been decorated to look like a Christmas tree each Christmas season. During the 2006 World Basketball Championship it was decorated with a large basketball net. Vilnius TV Tower became the biggest basketball hoop in the world during the 2011 FIBA European Basketball Championship; the hoop was 35 metres in diameter with a 40 metre-high net, assembled at a height of 170 metres.

The lighting of the giant hoop took 2,560 metres of 545 bulbs. Bungee jumps are available to the public from the roof of the observation deck; the Vilnius TV tower official website SC Lithuanian Radio and Television Centre official website Vilnius Television Tower at Structurae
