By 1780, many parts of the castle had fallen into a bad condition and were repaired in a Georgian style by Sir Benjamin Hammet, a banker of Lombard Street, London, and the Member of Parliament for Taunton. In 1786 he purchased the grant as bailiff and keeper of Taunton Castle in the names of his sons and his nephew. He put on a new roof, inserted many windows and recast many other details all round the castle. During the 18th and 19th centuries the Great Hall was used for public meetings.
