The city, located over a hill by the river Mondego, was called Aeminium in Roman times. During late Antiquity it became the seat of a Diocesis substituting the nearby city of Conímbriga, which had been captured and partially plundered by invading Germanic peoples in 465 and 468, adopting later the name of the destroyed city. After the Roman city of Civita Aeminium, between 586 and 640, the Visigoths altered the name of the town to Emínio. The Moors ocuppied Coimbra around the year 711, turning it into an important commercial link between the Christian North and Muslim South. The city was definitely reconquered by Ferdinand I of Leon in 1064.
