Between 1403 and 1412 Thomas Wolvey was engaged to build a clock tower in the Market Place. It is the only extant medieval town belfry in England. The original bell, named for the Archangel Gabriel sounds F-natural and weighs one ton. Gabriel sounded at 4 am for the Angelus and at 8 or 9 pm for the curfew. The ground floor of the tower was a shop until the 20th century. The first- and second-floor rooms were designed as living chambers. The shop and the first floor were connected by a flight of spiral stairs. Another flight rises the whole height of the tower by 93 narrow steps and gave access to the living chamber, the clock and the bell without disturbing the tenant of the shop.
