Small castle with great views, a few audio clips recreating life in the castle as it would have been during Henry VIII ‘s time.

So in strong winds the bridge is closed. However, the rune can also be seen very clearly from Hotel Camelot and at the café below the peninsula.

Nice little town with lots of knick-knack shops about magic, knight's tower, dragons and esotericism. It is very touristy but still nice and there is good food and drink. There isn't much left of the old castle on the rock, but there is still a special atmosphere here with great views. Merlin's cave on the beach is also worth a visit.
