One day when we were visiting Roger Lezeau we happened to mention to him that we had seen a rather odd building at the bottom of rue de la folie in Preuilly. We couldn't work out what its function might have been. He immediately knew which building we must be talking about and drew a rough sketch of the front to confirm it. We asked him if it was the folly that the street is named for, but he said, no, the folly is prehistoric, and on the farm at the top end of the street. He told us the farmer had offered to sell the stones of the 'folly' to the local museum. Roger thought this was outrageous, as such things should be offered as a gift, to benefit everyone.
He told us that the building was 19th century, in the Neo-classical style, with accommodation above and a large wine cellar (cave à vin) below. He was particularly keen to dispel any ideas we might have that the building was a chapel, either Catholic or Protestant. It sounded like there is a local myth about it being the long-lost (16th century) Protestant chapel of Preuilly and he was fed up with having to disabuse people.
I said that it was nonetheless an interesting building. He snorted and said that it was curious but not interesting! (I don't think Roger's tastes find much to their satisfaction in the 19th century – he is much more interested in the Middle Ages.)
