4. Why was the wall important?
The Roman Empire used buildings to convey power, wealth and greatness through its temples, markets, government buildings. The entrance, known as London Gate, is where Watling Street entered the city of Verulamium. The gate is wide enough to allow vehicle access and defended by two towers.
The verdict
Sections of the wall remain in Verulamium Park that formed the original perimeter of the Roman City. The preservation of the wall is impressive, and bands of tile are used to strengthen it. The best view is from the top of Verulamium Park with King Harry lane behind you. This overlooks the Roman Wall, Verulamium Park and lake, with St. Albans Catherdral visible on the skyline.
There is not much to see with the wall itself, but combined with the other historical sites and attractions would make a visit to Verulamium Park worthwhile.
