Perched at the foot of Mont Saint Clair, the Théâtre de la Mer overlooks the Mediterranean. Every summer, this 18th-century fortification hosts the major cultural events of the ‘singular island’.
In 1710, the town was invaded by the English, who had come to support the revolt of the Cévennes Protestants. The capture of Sète lasted only three days, but this event demonstrated the need to protect the town from external attacks. Fort Saint-Pierre was then built, based on plans by a pupil of Vauban: Antoine de Niquet.
Built on seven platforms arranged in an amphitheatre facing the sea and equipped with gun batteries, Fort Saint-Pierre operated in tandem with Fort Richelieu, built in 1745 to reinforce the town’s defences. The latter now houses the semaphore station, from which the French Navy monitors the Gulf of Lion.
