The search for chateaux

I've met a few of the Prof's friends -- the first ones who aren't related to school. We've spent two days at a beach, have bought a few odd things in some small clothing markets and are about to set out to tour some castles. I've seen them from afar in a few of the medieval villages that we've visited, but this will be my first time inside. I'll try to take some pictures if it doesn't get me kicked out.
