Roman Wall of St Albans

The Roman Wall of St Albans, which was built between AD 265 and 270 to defend the Roman city of Verulamium, can still be traced for most of its two-mile circuit.

At its peak, the massive structure towered at a height of 5 metres and was topped by a walkway protected by a 1.8 metre parapet - giving some indication of the importance placed on what was then Roman Britain's third largest town.

Although today the wall no longer stands quite so tall, parts of the structure do still reach the impressive height of 4 metres, and the surviving foundations of two towers and bastions as well as the remains of the impressive London Gate make the wall well worthy of a visit.
