We recently had a day out at Snowshill Manor, which is a National Trust property in the Cotswolds. This proved great fun for both us and the kids.
Snowshill is not your run-of-the-mill NT property displaying the usual array of fine furniture and artworks. Rather, Snowshill was the home of Charles Wade, a tireless collector of artefacts from around the world. The house is stuffed full of eclectic objects ranging from Samurai armour, to children's toys, to sea chests with complex locks... Everywhere you look, there is something unusual and fascinating to discover.
During Wade's lifetime, the manor house became so full that he had to move into the adjacent priest's house. You can see the living room/kitchen, bedroom and bathroom in the priest's house as Wade lived in them --and even here there are yet more objects from his collection.
The manor has beautiful terraced gardens (including a model village!) that are also fun to explore, and you can picnic in the orchard.
We rounded our day off with tea in Huffkins tea room in nearby Stow-on-the-Wold. If you haven't yet, you should try the Huffkins lardy cake -- a real treat!
