Rocher des deux Frères, Rock formation on Mediterranean coast in Agde, France.
Rocher des deux Frères comprises two volcanic rock towers that rise from the Mediterranean Sea to a height of approximately 21 meters above the water surface. These distinctive formations stand near Cap d'Agde and form a prominent feature of the coastal landscape.
These volcanic formations originated approximately 750,000 years ago through submarine eruptions, marking the southern terminus of the Auvergne volcanic chain. They reveal the geological history shaped by ancient volcanic activity in this Mediterranean region.
Local legend speaks of two brothers who rescued an injured mermaid and were turned to stone by Poseidon following a deadly quarrel. This tale remains woven into how people talk about and understand the rocks today.
Access to the rocks is primarily available from the water, with several diving clubs in the vicinity offering exploration opportunities. The clear Mediterranean waters make it straightforward to explore both the formations and underwater sites.
The nearby Grande Conque beach features black and dark gray volcanic sand, distinguishing it from other Mediterranean beaches. This dark sand originates from the same volcanic events that shaped the rocks themselves.

Agde and the adjoining Cap d'Agde on the Mediterranean coast offer photographers a mix of volcanic rock formations, black sand beaches, and historic architecture. The 12th-century Cathédrale Saint-Étienne stands in the old town center, built from local basalt. Fort de Brescou, a 16th-century fortress on an offshore island, marks the region's maritime history. The port area and the Musée de l'Éphèbe, which displays Greek and Roman artifacts recovered from the Mediterranean, document the city's long seafaring tradition. The coastline provides varied subjects, including Mont Saint-Loup, a 114-meter (374-foot) extinct volcano, Plage de la Grande Conque with its black pebbles, and the volcanic cliffs at Cap d'Agde. The Thau Lagoon near Sète, Île des Loisirs with its recreational facilities, and the Hérault River mouth at Le Grau d'Agde extend the photographic possibilities. Additional sites include Château Laurens, an Art Nouveau building, the Round Lock on the Canal du Midi, the Brescou lighthouse, and the 14th-century Chapelle Notre-Dame-de-l'Agenouillade.
