There is plenty on the internet about the Chateau of Charge (Razines), but almost nothing about the chapel that sits on the other side of the road. The chateau was originally built in 1170(ish), but I can't work out if the chapel is the chapelle mentioned on the monumentum page.
Certainly the wall paintings don't appear to be 17th or 18th century, to us they look more like late 19th to mid 20th century.
We discovered the chapel when I was plotting a route to a winery with Célestine and some clients. I thought it would make a good location for taking photos, but didn't expect it to be open.
