Gesoriacum, Roman archaeological site in Boulogne-sur-Mer, France
The ancient port complex of Gesoriacum contains remains of Roman military structures, trading facilities, and defensive walls near the Liane River estuary.
In 43 CE, Emperor Claudius assembled his fleet at Gesoriacum to launch the Roman invasion of Britain, establishing its role as a strategic naval base.
Archaeological excavations at Gesoriacum reveal evidence of maritime trade networks connecting Gaul with Britain through pottery, coins, and imported goods.
The archaeological remains of Gesoriacum lie beneath modern Boulogne-sur-Mer, with sections visible within the medieval city walls and local museum collections.
The site features traces of a Roman lighthouse built under Emperor Caligula in 39 CE, which served as a navigation point for ships crossing the Channel.
