The Fort de Portzic was built near the town of Brest by Vauban between 1693 and 1699 as part of the defences of the goulet de Brest.
[1] It faces the pointe des Espagnols and was improved and enlarged over time (including the Phare du Portzic in 1848 and a semaphore station in 1987), since it formed the town's last and innermost defence.
The buildings on the site remain in military use.
Nearby is the lighthouse Phare du Portzic.
