The Tholsel on High Street, Kilkenny, Ireland was built in 1761 by Alderman William Colles as place for collecting tolls, but has also been used as a customs house, a courthouse and a guildhall. It is used today as the city hall, and this is the name by which many local people know the building.Key features of the building are the open arcade on the ground floor, which straddles the pavement; the copper-clad octagonal tower projecting from the hipped slate roof; the clock, and the tower's viewing platform.
