The current configuration of Port Vauban dates from the early 1970s. Its first dike was built in the 16th century, followed by a jetty in 1648. The ramparts of the fortified town and the port were redeveloped by Vauban in 1680 as part of King Louis XIV's belt of fortifications. The silting up of the port forced new excavations between 1775 and 1778 and the reconstruction and extension of the breakwater sheltering its entrance. The current quays were created in the 18th century and extended in 1830. In 1958, the wharves fitted out to accommodate an oil terminal and a naval airbase at the beginning of the 20th century were rebuilt, and, in 1965, Port Vauban was extended by a breakwater in Saint-Jaume and a groin under Fort Carré. In the 1980s, the sea wall was extended by 984 ft (300 m) to better protect the entrance to the port and accommodate large-tonnage yachts.
