This is an English Heritage site. The fee to enter is £4.40. Unlike many other EH sites we’ve been to, this one didn’t have an audio tour which was a shame as there is more to learn about the place than you pick up from just wandering about. There aren’t any information boards to read as you walk around either. But, it was a sunny day, and it was nice to wander among the ruins imagining what their history held. Be sure to check out the huge beech tree on the far side of the ruins which has grown on top of the derelict wall. I didn't notice a cafe - but there are a few picnic tables.
