I wrote part one over 17 months ago, but I said I would be back with better photos, and here I am!
We were at Boussay with my brother and his wife; JB and Rosie. The grounds of the chateau are open to the public, so we wandered in and took some photos. As far as I know the chateau itself is never open to the public which is a pity as it looks a really interesting building. Most of the building is 18th century, except for the round tower and the gatehouse to the left of it, which are 15th century.
The moat is fed by springs (something I found out only yesterday) and is permanently full.
