Located in London's Trafalgar Square, it houses a synoptic collection of pre-1900 paintings assembled by government purchase and donation. It is home to British masterpieces including John Constable's The Haywain and both Rain, Steam and Speed and The Fighting Temeraire by J. M. W. Turner. The museum also boasts several major highlights of European painting, from arguably the best known of Vincent van Gogh's Sunflowers series to exemplar Baroque works like Caravaggio's Supper at Emmaus, The Judgment of Paris by Peter Paul Rubens, and the Rokeby Venus of Diego Velázquez. Major works of the Italian and north European Renaissance are also represented, including Jan van Eyck's The Arnolfini Wedding, Hans Holbein's The Ambassadors, Titian's Bacchus and Ariadne, Raphael's Portrait of Pope Julius II, and the later of Leonardo's two versions of Madonna of the Rocks.
