Heritage of Agde
Agde was founded 2,600 years ago by Greek colonists from Phocaea as Agathé Tyché — "Good Fortune" — and is one of France's oldest cities. Its black volcanic basalt, fortified Romanesque cathedral, France's only underwater archaeology museum and its volcanic island fortress compose an exceptional heritage on the shores of the Mediterranean.

Agde — 2600 years of history
Around 525 BC, Greek sailors from Phocaea — the same city that founded Marseille — dropped anchor at the mouth of the Hérault and settled permanently. They named their new colony Agathé Tyché(Good Fortune), appreciating the natural harbour that opened onto Iberian and Gallic trade routes. Agde is thus one of the oldest cities in France, founded decades before Rome set foot in Gaul.
What immediately strikes any visitor to Agde is the colour. Not the luminous white limestone of Montpellier or Sète — but a deep, solemn black. This comes from the volcanic basalt of Mont Saint-Loup, an extinct volcano standing guard over the town at 112 metres. This stone, used for centuries in every building in the old town, earns Agde its nickname: the Black Pearl of the Mediterranean.
In the 17th century, two giants of French engineering left their mark: Pierre-Paul Riquet built the Canal du Midi with Agde's unique round lock (UNESCO 1996), Vauban fortified Fort Brescou on its volcanic island. The Éphèbe Museum (1985) is today France's only underwater archaeology museum, home to the bronze Éphèbe of Agde, a Greek statue from the 4th century BC.
