In the picturesque village of Aubeterre-sur-Dronne, in the Charente region, is to be found a subterranean church, carved out of solid rock. Originally, in what must have been a major feat of both architecture and engineering, it was dug out from beneath the local chateau, which no longer exists.

They call it a church, but in terms of sheer scale it could easily pass for a cathedral.
