Wales is called the “castle capital of the world” for a reason. The Normans had a tough time of it here and built over 600 fortresses. As a county, Monmouthshire is blessed with a wealth of attractive ruins and iconic wonders that have seen better days. Join Chronicle reporter Tim Butters as he takes a tour of Monmouthshire’s castles in the final part of a two-part series. This week, we visit Chepstow, Grosmont, Skenfrith, Whitecastle, and, of course, Monmouth.
