'Looking to Sea' takes us from Vanessa Bell's painting of Studland Beach, one of the first modernist paintings in Britain, to Paul Nash's post-war art that bore the scars of his experience in the trenches, to Martin Parr's photographs of seaside resorts in the 1980s. Lily Le Brun embraces ideas from modernism and the sublime, the impact of the world wars and the influence of America, to issues crucial to our world today like the environment and nationhood.
