The round Agde lock belongs to the technical facilities of the Canal du Midi in Languedoc. In the past, the shape of the airlock allowed boats to rotate into the pool. Currently, the mechanism has been changed in connection with work on unblocking the channel at the end of the 20th century.
The original construction of the lock is from the second half of the 17th century. Established in the place where the Herault River joins the Canal du Midi. For this reason, it has three outlets, not two, as in traditional locks. The first sluice was built of volcanic tuff from the area. It uses gears and locks driven by muscle strength. Over time, they were replaced by mechanical closures. The lock is one of the technical monuments and is one of the oldest of its kind in France.
