Montpoupon, a hunting lodge.

This is the Château de Montpoupon. It was built in the 15th and 16th centuries

 on the site of a 13th century fortress of which only the tall round towers remain. 
It's only a short drive south of Montrichard, and a slightly longer one from Saint-Aignan.

I don't think I took this photo of Montpoupon; I think our friend Sue from California did when

she was here for a few months in 2006. I found it on my laptop this morning.
