The Town Hall in the Market Square is a much-adapted building originally dating from circa 1648 when it was referred to as a 'Market House'. In 1721 a new construction of Portland Stone was built containing a poultry and butter market. The building fell into disrepair and was substantially rebuilt around 1812. In 1888 it became the property of Horsham Urban District Council and was again largely rebuilt. The present building is essential of late-Victorian construction, though preserving some aspects of the earlier buildings. It has been used as council offices and as a magistrates court and more recently housed the Horsham Registry Office on the upper floor. The ground floor was still used as an occasional market place until the Town Hall was closed to be let as a restaurant.
