"Set in London’s busiest open space, Trafalgar Square, this is the grandmother of galleries with more than 2,300 paintings spanning the 13th to the 19th centuries: Heavyweights include Van Gogh’s Sunflowers, Velazquez's Rokeby Venus, and Constable’s six-foot long The Hay Wain. It gets packed at weekends, but its so large that you can usually find a quiet corner. You can download an audio tour covering the museum's highlights, but you can also curate your own by selecting the paintings you want to see before you arrive. The seasonal exhibitions are the only ones you’ll pay for, and as you'd expect, most are spectacular ranging from Lucian Freud to Titian." - Ramsay Short, Sonya Barber
