A small, intimate and very interesting museum within a building which is a bit of a maze, but all the more interesting for that. Staff, including some costumed spinners and a calligrapher, very helpful and willing to get involved with visitors. Artefacts, historical documents and information are well displayed and tell the story of the area very well.
The informal parts of the grounds are good for kids to play games and roll around, and for everyone to stroll in the shade. The walled garden is a major project that is beyond the 'work in progress' development stage and is now a fascinating and well-managed place of interest to non-enthusiasts as well as garden geeks like me. It also has a small café.
Which brings me on to my one complaint, which I won't allow to affect the 5 rating. The main café in the castle courtyard, while having really good food and drinks, had some unbearably noisy machinery. Whether this was normal, or just some sort of air-con on what was a hot day, I don't know, but it drove us to the tables outside.
