At the heart of the British Library in London, stands a tall glass tower - the King's Library Tower,
The six-storey Tower houses books collected by King George III (reigned 1760-1820) and is considered one of the most significant collections of the Enlightenment, containing books printed mainly in Britain, Europe and North America from the mid 15th to the early 19th centuries. It consists of 65,000 volumes of printed books, with 19,000 pamphlets.
The collection's home at the Library's St. Pancras site is the six-storey King's Library Tower, designed specifically for the purpose by the building's architect Sir Colin St John Wilson (1922-2007). Many of the books are on view to visitors behind UV-filter glass which, together with the environmental control system, helps maintain appropriate light, temperature and humidity levels. Behind the moveable bookcases containing George III's books, there is in fact another row of shelves containing a similar collection formed by Thomas Grenville (1755-1846). The King's Library remains a working library, and throughout the day volumes are retrieved for readers working in the Rare Books and Music Reading Room.
If you haven't visited, you should put it on your to do list.
