In 1861, as the mouth of the Penfeld River could no longer meet the needs of the naval and merchant fleets, this port was created; its commercial traffic now reaches 3 million tonnes annually. A hub for ship repair, it houses the world's largest dry dock, capable of accommodating oil rigs. You can view the facilities from the La Pérouse breakwater promenade, while a walk along the quays—closer to the city center—offers a view of all these maritime activities.
