Barcelona - A settlement in Tarraconensis also known as Barcino
Barcelona - or Barcino - is a city in Spain which was made into a Roman 'castrum' in 15 BC. It later became a colony, and minted its own coins; some from the era of Galba survive. It was also a mint under Constantine III, from 409-411 AD.

In the Middle Ages Barcelona became the capital of the County of Barcelona. After merging with the Kingdom of Aragon, Barcelona continued to be an important city in the Crown of Aragon as an economic and administrative centre of this Crown and the capital of the Principality of Catalonia.

The city was conquered by the Visigoths in the early 5th century, becoming for a few years the capital of all Hispania. After being conquered by the Arabs in the early 8th century, it was conquered in 801 by Charlemagne's son Louis, who made Barcelona the seat of the Carolingian "Hispanic March" (Marca Hispanica), a buffer zone ruled by the Count of Barcelona.
