Fantastic fun. We had a 6 year old and a 2 year old with us and they both enjoyed it. We got a guided tour from the Curator himself and he made it very interesting and quite funny also. There was also a man in the lobby who was teaching archery and all about different types of bows and arrows....needless to say that the 6 year old LOVED that! It only cost €14 for the guided tour, and we were able to go back around as often as we liked on our own afterwards.
