Bastion Saint-Jaume

This is the Saint-Jaume Bastion. Entry is free but subject to opening hours, so if it’s closed when you arrive, be sure to check the schedule so you can come back. This site has a long history—back in Roman times, it was home to a temple, then a chapel, and eventually a fortified tower built to protect the city from invasions. That tower was destroyed in the 17th century and replaced by a naval construction bastion, which remained active until 1985. One of the most famous ships ever fitted out here was the Calypso, used by Commander Cousteau. You’ve probably heard of him—he was a naval officer and, above all, a pioneering oceanographer who had a major impact on scientific research in the late 20th century. Through his explorations, he revealed the fragility of the seabed and the urgent need to protect it for future generations. A true defender of the environment, he dedicated his life to convincing world leaders that ecology was a global responsibility—and that action was needed. The bastion was eventually demolished in 1985, once it was no longer in use, but you can still see the remains of this impressive structure that once stood facing the sea at the end of Quai Henri Rambaud.
