Town Hall – A new Tholsel was erected in 1753 by the corporation, in lieu of that taken down in 1745. It contained an exchange, Council House, Custom House and Grand Jury room. It was situated outside the town walls beside the Water Gate. The town's Water Gate was built in the 13th century to provide access through the town walls to the docks. Also known as Cromwell's Arch, it was from here that Oliver Cromwell left Ireland in 1650, having overwintered in the town after his campaign in Ireland.
