Monolithic Church, Saint-Émilion

The largest underground church in Europe, carved out of the solid limestone hill beneath Saint-Émilion in the 11th and 12th centuries. Its tall nave, with pillars cut from the rock, sits under the village square, with a 68 m bell tower above.

It can only be visited on a guided tour from the tourist office, which also includes the catacombs and the hermitage cave of St Émilion, the monk the town is named after. Afterwards, climb the bell tower for a view over the village's rooftops and the surrounding vineyards, a UNESCO World Heritage landscape.
