It's the largest castle in Wales and we went there. Absolutely brilliant.
A rather last minute plan on Saturday, we weren't sure if the weather would hold out, but it did and ended up being a resplendent afternoon.
The castle comes complete with a moat, drawbridge, tower, corn mill, trebuchet, and some nasty looking moat fish (to guard the castle no doubt). We had the best time exploring all around it. Jerremy said it was the best castle he's ever seen. I would put it in my top 5, easily. It's a pretty nice castle. They've been restoring it since the 1930's. Apparently, there used to be a Roman fort beside it. Romans came in AD 75 and stayed till about the 400's. They have yet to excavate it.
Our time is so short in the span of history.
