Genuine French Protestant church, post-Revocation of the Edict of Nantes. (Grotte des Camisards, Rochegude, history)
I've personally been in this one, it has some nice acoustics - you just have to be careful not to hit your head going in, the entrance is about 1.5 meters tall but gets bigger the deeper you go. No stained glass windows, but the forest is beautiful! How amazing to see God's glory all around you when you step out. And how gracious is God that He'd come in such lowly places to comfort and uplift His people.
