Trafalgar Square is the central square of London, built to commemorate the Battle of Trafalgar of 1805 in which the British Navy defeated the Spanish Navy at Cádiz (Spain).

In the centre of the square, the monument to Viscount Horatio Nelson, commander of the Trafalgar fleet, whose sacrifice in battle achieved victory on the Spanish coast.

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. Prominent buildings facing the square include the National Gallery, St Martin-in-the-Fields, Canada House, and South Africa House.

Today the square is often used for community gatherings, political demonstrations and to celebrate sporting events.
