Grottes de Régulus

The Grottes de Régulus are cave dwellings carved into limestone cliffs in Meschers-sur-Gironde along the Gironde estuary, stretching roughly 300 meters with cliff faces reaching about 25 meters above water level. Multiple chambers and terraces connect throughout the site, creating a network of interconnected spaces within the rock face.

During the 19th century, these natural cavities were transformed into permanent homes, with residents carving out living spaces within the limestone rock. The caves served as dwellings for families across generations who adapted their lives to the conditions of stone and water.

The caves take their name from Le Régulus, a French warship that was deliberately set on fire in 1814 to keep it from British forces. This naval history remains woven into how people today understand and connect with the site and its limestone dwellings.

The visit involves stairs and narrow passages, so comfortable footwear is essential and those with mobility concerns should ask in advance which areas are accessible. The best time to visit is on overcast days or early in the day to avoid intense sun exposure on the cliff face.

Some of the cave chambers were equipped with fireplaces to help residents stay warm and cook, and soot marks remain visible on ceilings today. These traces show how resourcefully earlier generations adapted to the challenges of underground living.
