A Roman settlement, named "Aeminium" existed here. When the neighbouring town "Conimbriga" got conquered and destroyed by the Suebes in 468, the survivors moved to "Aeminium" - and renamed it. The Visigoths under King Wittiza named the town "Eminio" later. In 714 the town was conquered by Muslim troops, who changed the name again.

Coimbra was finally recaptured in 1064 by King Fernando de Castilla y León. Coimbra became the second capital of the Kingdom of Portugal (after Guimarãesin) 1139, a status that moved to Lisbon in 1256. The University of Coimbra, founded by Denis of Portugal (aka "Dom Dinis") in 1290, is one of the oldest in Europe.

Today more than 20% of the Coimbra´s population are students at the university. So the number of coffee shops and small bars in the old (and hilly) part of the town is no surprise.
