The National Portrait Gallery (NPG) is an art gallery in London housing a collection of portraits of historically important and famous British people. It was the first portrait gallery in the world when it opened in 1856. The gallery moved in 1896 to its current site at St Martin's Place, off Trafalgar Square, and adjoining the National Gallery. It has been expanded twice since then. The National Portrait Gallery also has three regional outposts at Beningbrough Hall, Bodelwyddan Castle and Montacute House. It is unconnected to the Scottish National Portrait Gallery in Edinburgh, with which its remit overlaps. The gallery is a non-departmental public body sponsored by the Department for Culture, Media and Sport.
