Chepstow Port Wall is a late thirteenth-century stone wall built with the duel purposes of defending the town and for the taxation of goods coming to the market, because there was only one gate this task was made much easier.
Quite a lot of the wall remains, although there are now more holes through it for roads and footpaths.
Originally the wall was 1,100 metres long semicircle which with the river as a natural barrier contained an area of 130 acres.
It is an interesting bit of history for a town that already boasts an impressive castle. You can see our film about Chepstow Castle HERE
