On Monday I took a cousin over to Caerphilly for an interview and while he was in there I took my camera for a walk arounf the out side of the castle. The first photo shows what tghe castle was like before Cromwell knocked it about a bit. It's difficult to see but there is a very narrow bit of moat going around the outside of the tower on the left as you are looking at it. Under the cut is what it looks like to day.
