Kate Norgate, England under the Angevin Kings… (1887)
“ The county of Anjou or “Angevin march,” the border-land of Neustria and Aquitaine, was for all practical purposes the border-land also of Neustria and of Britanny. Angers, with its Roman citadel and its Roman walls, perched on the crest of its black slate-rock, at once guarding and guarded by the two rivers which flowed round its foot, was a far mightier fortress than Nantes; Angers, rather than Nantes, was the true key of the Loire valley, and the stronghold of the Neustrian border against all attacks from the west, whether by land or by sea. ”
