A Victorian country house, now owned by English Heritage, it has marvelous gardens which range from formal beds and lawns near the house to a temple-style summer house, to a rockery wilderness with tunnels and paths leading up and down the slopes, to woodland and rose gardens (a little past their past when we visited) to a pergola draped in grapevines.
And, of course, there was cake :)
All in all a good way to break the journey - far pleasanter then the motorway services we stopped at on the way home.
