The Monmouth town walls and defences comprise the defensive system of town walls and gates built in Monmouth, Wales between 1297 and the early part of the following century. Wye Bridge Gate, East Gate (Dixton Gate), Monk`s Gate, and Monnow Bridge Gate were access points to the town. West Gate, across Monnow Street, also provided access. Only the Monnow Bridge Gatehouse survives intact, albeit in a substantially modified version from the original.
