Chepstow Castle is located in Monmouthshire. Once of South Wales’ numerous and wonderful medieval remains, the castle rests on top of cliffs overlooking the River Wye. Built in the 11th century, it is the oldest surviving post-Roman stone fortification in the whole of Britain.
I visited it a few weeks ago on a family day out, and would recommend the tour if you’re in the area. Here are a few pictures – ignore the shit weather.
