Clock Gate Tower – In 1777, the town's Clock Gate Tower was built on the site of Trinity Castle, part of the town's fortifications. It was used as a prison during the rebellion of 1798. The military hanged suspects from a pole lashed from the lower windows to the corner of the first house on South Main Street. Thomas Gallagher was one of those hanged for trying to seduce a soldier from allegiance to his regiment. Numerous forms of torture were conducted therein including thumb screws, pitch-cap, rack and flogging. The Clock Gate served the town as gaol and public gallows until 1837. It later became a family home, until the last family left in 1959
