UK - England to Wales

There are signs in English and Welsh all throughout Chepstow Castle ruins explaining what each area was used for. A few facts that interested us: Marten's Tower was so named because Henry Marten was imprisoned here by Charles 11 because he was one of those who signed the death warrant of Charles 1; the latrine in the Earl's chamber empties directly into the River Wye below; The Great Tower was built on orders of William 1 and they used recycled orange Roman tiles as part of the wall structure.
