Today I found just such a chateau online. Isn't she a beaut?
She's in Bauné, which I have no idea about but she's close to a little town called Angers, and sacré grace, what a place. Even little unknown towns in France, look like sets for the most romantic movie ever made...sigh
Picture credits of town of Angers. 1 and 3 are from Philippe Stoop. 2 is JThillie. 4 is Phillippe Vasseur. All of the Angers pics were taken from google maps. The chateau pics were from arkadia.com a real estate site.
