Brantôme in the Dordogne is crossed by the Dronne river.

Part of its town centre is surrounded by this river which forms an island, which earned it the nickname "Venice of the Périgord". It is best known for its Benedictine abbey comprising an abbey, a cloister, an 11th century Romanesque bell tower which was built independently of the other buildings on a rocky cliff. This abbey was troglodyte at the beginning of its history, received the relics of Saint Sicaire and became a very popular place of pilgrimage.
