Trafalgar Square is a public square in the City of Westminster, Central London. Its name commemorates the Battle of Trafalgar, a British naval victory in the Napoleonic Wars with France and Spain that took place on 21 October 1805 off the coast of Cape Trafalgar, Spain. The 52 m (169-foot) Nelson's Column at its center is guarded by four lion statues. A number of commemorative statues and sculptures occupy the square, but the Fourth Plinth, left empty since 1840, has been host to contemporary art since 1999.
