Winchelsea retains its medieval setting on a hill surrounded by largely empty marsh, the original layout of the planned town and the largest collection of medieval wine cellars in the country with the possible exception of Norwich and Southampton. It also retains three of the four town gates and several original buildings, including the parish church, which is dedicated to St Thomas the Martyr. Another church, St Leonard's, was later the site of a windmill, which was blown down in the Great Storm of 1987. Some of the original 13th/14th-century fortifications can still be seen at the Strand Gate and Pipewell or Ferry Gate. The scale of the original plan for New Winchelsea can be judged by the site of the "New Gate", over half a mile outside the current town.
