Flatford Mill by Constable 'Scene on a Navigable River' (1816-17) John Constable (June 11, 1776 - March 31, 1837) was a British Romantic artist. Flatford Mill is on the River Stour close to the Suffolk-Essex border. The Centre buildings, particularly the Mill and Willy Lott's House, are instantly recognisable since they feature in many paintings by John Constable. ?006 TopFoto
