The Chapel was erected in 1785 and John Wesley himself preached here. Services are still held in it occasionally.
Wesley first visited Winchelsea in 1772 and the townspeople were so taken with his preaching that they responded in 1785 by building a preaching house, Winchelsea Chapel. Four years later Wesley returned to preach in the Chapel and was in Winchelsea again on 7th October 1790 when he preached his last open air sermon under a tree in the town centre. The Chapel retains many of its original features, including the pulpit, and is a place of great peace and charm.
