After visiting the garden & house we went exploring to find the Chateau de la Roche-Guyon our host Monsieur Werth had told Kent about. We found it, with parts of it dug deep into a limestone cliff, parts being from the middle ages & others 18th century & everything in between. It had been the home of Rochefoucault & later Rommel. It is currently hosting some very interesting (& some pointless) contemporary art installations. Nobody else was there, so we wandered alone through the whole thing.
