National Gallery. The National Gallery is an art museum in Trafalgar Square in the City of Westminster, in Central London. Founded in 1824, it houses a collection of over 2,300 paintings dating from the mid-13th century to 1900. The Gallery is an exempt charity, and a non-departmental public body of the Department for Culture, Media and Sport. Its collection belongs to the government on behalf of the British public, and entry to the main collection is free of charge. It is among the most visited art museums in the world, after the Louvre, the British Museum, and the Metropolitan Museum of Art. Unlike comparable museums in continental Europe, the National Gallery was not formed by nationalising an existing royal or princely art collection. It came into being when the British government bought 38 paintings from the heirs of John Julius Angerstein in 1824. After that initial purchase the Gallery was shaped mainly by its early directors, notably Sir Charles Lock Eastlake, and by private donations, which today account for two-thirds of the collection. The collection is small compared with many European national galleries, but encyclopaedic in scope; most major developments in Western painting from Giotto to Cézanne are represented with important works. It used to be claimed that this was one of the few national galleries that had all its works on permanent exhibition, but this is no longer the case. The present building, the third to house the National Gallery, was designed by William Wilkins from 1832 to 1838. Only the façade onto Trafalgar Square remains essentially unchanged from this time, as the building has been expanded piecemeal throughout its history. Wilkins's building was often criticised for the perceived weaknesses of its design and for its lack of space; the latter problem led to the establishment of the Tate Gallery for British art in 1897. The Sainsbury Wing, an extension to the west by Robert Venturi and Denise Scott Brown, is a notable example of Postmodernist architecture in Britain. The current Director of the National Gallery is Gabriele Finaldi. The late 18th century saw the nationalisation of royal or princely art collections across mainland Europe. The Bavarian royal collection opened to the public in 1779, that of the Medici in Florence around 1789, and the Museum Français at the Louvre was formed out of the former French royal collection in 1793. Great Britain, however, did not emulate the continental model, and the British Royal Collection remains in the sovereign's possession today. In 1777 the British government had the opportunity to buy an art collection of international stature, when the descendants of Sir Robert Walpole put his collection up for sale. The MP John Wilkes argued for the government to buy thisinvaluable treasure and suggested that it be housed in a noble gallery. to be built in the spacious garden of the British Museum Nothing came of Wilkes's appeal and 20 years later the collection was bought in its entirety by Catherine the Great; it is now to be found in the State Hermitage Museum in St Petersburg. A plan to acquire 150 paintings from the Orléans collection, which had been brought to London for sale in 1798, also failed, despite the interest of both the King and the Prime Minister, Pitt the Younger. The twenty-five paintings from that collection now in the Gallery, including NG1, arrived later by a variety of routes. In 1799 the dealer Noel Desenfans offered a ready-made national collection to the British government; he and his partner Sir Francis Bourgeois had assembled it for the king of Poland, before the Third Partition in 1795 abolished Polish independence. This offer was declined and Bourgeois bequeathed the collection to his old school, Dulwich College, on his death. The collection opened in 1814 in Britain's first purpose-built public gallery, the Dulwich Picture Gallery. The Scottish dealer William Buchanan and the collector Joseph Count Truchsess, both formed art collections expressly as the basis for a future national collection, but their respective offers were also declined. Following the Walpole sale many artists, including James Barry and John Flaxman, had made renewed calls for the establishment of a National Gallery, arguing that a British school of painting could only flourish if it had access to the canon of European painting. The British Institution, founded in 1805 by a group of aristocratic connoisseurs, attempted to address this situation. The members lent works to exhibitions that changed annually, while an art school was held in the summer months.
