showing the territory of the
Andes or
Andecavi along the Loire (ancient name Liger) The territory of the Andecavi roughly corresponded with the
diocese of Angers, Anjou, in the department
Maine-et-Loire in present-day
France. Although Caesar locates the Andes "near the
Ocean", they held no coast and were located inland along the
Loire river. Their chief town, Iuliomagus (modern
Angers), developed from a densely occupied Late Iron Age settlement. By the late 1st century BC, a fortified
oppidum of roughly 9 hectares stood on a promontory above the
Maine. Finds of military material point to a continued Roman presence from the mid-1st century BC. In the early 1st century AD, the settlement was reorganised and laid out with a street grid within a short period, suggesting deliberate planning rather than slow expansion. After the Augustan reorganisation in the late 1st century BC, the settlement became the capital of the
civitas and probably adopted the name
Iuliomagus at that time. It then spread beyond its earlier limits, covering about 70 hectares by 10–15 AD, with new housing and workshop areas, including for pottery and ironworking. Some streets were marked out in advance of later construction under Tiberius. Buildings continued to be made mainly of wood and earth, with stone architecture appearing only gradually. ==History==
