Overview

History & context

Gesoriacum, renamed Bononia in the late 3rd or early 4th century, was the principal Roman port on the Gallic side of the Channel, situated on the estuary of the Liane. Active from the early 1st century AD through Late Antiquity, it served as the main embarkation point for Britain and the home base of the Classis Britannica, the British fleet, from the Flavian period until the mid-3rd century. The settlement comprised an upper fortified town on the hill and a lower civilian and harbour quarter along the river.

Significance

Historical significance

It was the linchpin of cross-Channel communication, supply, and troop movement to Britain—Claudius launched his invasion force from here in AD 43, and Caligula's earlier theatrics on this coast (the famous order to gather seashells) are traditionally located here. As headquarters of the Classis Britannica and a key node on the Agrippan road network from Lugdunum, it was administratively and militarily indispensable; it was also the base from which Carausius launched his usurpation in 286, and Constantius Chlorus recovered it by siege in 293.
