Built around 1676, the Bagnas lock is a simple lock on the Canal du Midi, located between Agde and the Étang de Thau. It is one of the last structures on the canal before its outlet at Les Onglous, where the canal joins the lagoon. In the immediate vicinity of Bagnas, a vast coastal wetland, the lock is also associated with a spillway intended to drain excess water.

In Agde, the Canal du Midi, built in the 17th century under the direction of Pierre-Paul Riquet, ensures the link between the Garonne river network and the Mediterranean. It notably connects to the Hérault and extends towards the Étang de Thau via the Canal des Onglous. This waterway, classified as a UNESCO World Heritage site, bears witness to the ambitious project conceived in the 17th century to connect the Atlantic to the Mediterranean.
