Why visit Caerwent?

Great town walls. Other things listed below, from Wikipedia.  But the walls are what students will remember.

It's a small settlement, and so the shape of the Roman town is still clear.

• 'CIVITAS SILVRVM' stone in the church porch.
• Large sections of the Roman town walls, rising up to 5 metres.
• Polygonal towers dated to the mid-300s.
• The Roman basilica and part of the forum.
• A Roman temple.
• A Roman courtyard house.
• Roman shops including a blacksmith's.
