On the seaward side of the Bassin de Thau, Sète harvests oysters and mussels, and stages historic water jousting tournaments, the joutes nautiques, in summer. It is a bustling fishing port in the lee of Mont Saint-Clair, with a host of fish restaurants, a sailor’s cemetery where the poet Paul Valéry is buried, and the Musée Paul Valéry, rue Denoyer, containing memorabilia of the local poet and a small but interesting collection of modern paintings. At the southern end of the Bassin de Thau (20 km), Agde was founded by the Greeks and built of black volcanic rock from Mont Saint-Loup. Cap d’Agde plays host to one of France’s largest naturist colonies, and a museum of antiquities, many recovered from the ‘ships’ graveyard’ offshore.
