This is the walk I was looking forward to the most, the chance to find out more about some of the castles in Gower. I love castles, and here in Wales we have more per square mile than any other country in the world. The Gower is absolutely teeming with them, some visible, some hidden beneath shifting sands and tangled woods. Today's walk was headed by archeologist Charles Hill along with the Gower Society, focusing on the buried castle of Penmaen, and the ruins of Pennard.
