Roman Bàrcino
The Roman walls that surround the heart of Barcelona embrace Bàrcino, which existed from the 1st century BC to the start of the Middle Ages. A city that began as a small colony and gradually grew to briefly become an imperial city.
The colony on Mount Taber
The area stretching between the Besòs and Llobregat river deltas, the site of today's Barcelona, was already populated in prehistoric times. Shortly before the start of the current era, it housed various settlements of native peoples, mainly Laietani. According to legend there was also a Jewish colony at the top of Montjuïc, which might explain where its name ("Jewish Mountain") comes from.
When the Romans arrived, between 15 and 13 BC, they were looking for the best place to found a colony between the prosperous Emporiae (Empúries), on the coast to the north, and Tàrraco (Tarragona), to the south. The spot they chose was the top of Mount Taber, a small hill facing the sea and looking over the plain, where Plaça de Sant Jaume is today. They had little difficulty in gaining control over the neighbouring settlements. The colony, called Julia Augusta Faventia Paterna Barcino, grew rapidly. A wall was built around it between the 1st and 2nd centuries, which was reinforced between the 3rd and 4th centuries and marked the perimeter that remained the same until the Middle Ages. It also kept the structure of a Roman city, with a forum at the centre from which two streets spread out in the form of a cross, the cardus and the decumanus, leading to the four entrance gates.
It is still possible to trace this structure today: Carrer Llibreteria, which starts in Plaça de l’Àngel where the Porta Sinistra, one of the gates in the wall, used to be, is the old cardus that crossed the city from north to south to the Porta Dextra, at the end of today's Carrer del Call; Plaça Sant Jaume, in the centre, extends a little to the south-east of where the Forum was in those days; and three modern streets, Bisbe, Ciutat and Regomir, follow the route of the old decumanus from the Porta Praetoria in the west to the Porta Decumana or Porta del Mar, in the east.
The presence of large domus in the city, houses with gardens and rich ornamental decoration, is proof of the presence of important property-owning families. And it was probably thanks to these families that the small Bàrcino gradually grew in size and significance. By the start of the 5th century money was already being minted in the city, establishing the first link with the imperial elite and placing it among the powerful cities.
Bimillennial city
19 August 2014 marked the bimillennial anniversary of the death of the Emperor Augustus, who founded the Roman colony of Bàrcino.
