Monmouth town walls and defences

Monmouth's town walls and defences form the remains of a medieval fortification system that once enclosed the town and showed its strategic importance on the border region. The most recognizable surviving structure is the Monnow Bridge Gatehouse, a well-preserved gateway spanning the Monnow river that once controlled entry into the settlement.

Construction of the defences began in 1297 under Edmund Crouchback after King Edward I granted permission to fortify this border settlement. Over the centuries, many sections deteriorated, though some structures like Dixton Gate have survived to the present day.

The gate names like Agincourt Gate reflect major historical events connected to the town's past. These names serve as visible reminders of how medieval Monmouth played a role in broader historical conflicts.

The main surviving sections are scattered throughout the town and are best explored on foot, with Monnow Bridge being the easiest to reach. Dixton Gate now forms part of a public house, allowing visitors to see its structure from inside if they enter the building.

The rivers Monnow and Wye were cleverly integrated into the defence system, forming natural barriers on two sides of the town. This geographical arrangement made Monmouth especially difficult to attack without needing extensive artificial fortifications on all sides.
