[dropcap]B[/dropcap]arcelona traces its origins over 2,000 years ago to the Roman colony called Barcino. It was founded by Emperor Augustus during the period of 15-10 BC, and the full Latin name of the colony was Iulia Augusta Faventia Paterna Barcino. Many remains of Barcino still exist in various locations of Barcelona’s Ciutat Vella (old town).
The area where Barcino was founded was already populated, mainly by the ancient Iberian Laietani tribe (from which the street name Via Laietana is derived). As a colony, Barcino was established to distribute land among retired soldiers. It was less important than the major Roman towns of Tarraco (Tarragona) and Caesaraugusta (Zaragoza). A wall was built around Barcino between the 1st and 2nd centuries AD, which was reinforced between the third and fourth centuries and it marked the city perimeter that remained until the Middle Ages. By the second century AD Barcino had a population of 3500–5000. The main economic activity was cultivation of the surrounding land, and its wine was widely exported.

In the Plaça Vila de Madrid lies a section of the Roman road called Vía Sepulcral, which lay outside the walls of Barcino. The road was lined by Roman tombs. A raised walkway in Plaça Vila de Madrid provides views of a section of the road and tombs dating from the second and third centuries AD.

4. Plaça Nova
In Plaça Nova features two sections of Roman wall and two square towers from the second city wall, built in the fourth century AD. It was here that carriages and pedestrians once entered the city from the north through the main gate called Porta Praetoria. This is where Carrer del Bisbe now begins and follows the same route as Decamanus Maximus, one of the two main streets in the Barcino. In the fifteenth century the adjoining Casa de l’Ardiaca (Archdeacon’s house) was built. Plaça Nova also features a reconstructed section of an aqueduct that led into Barcino and a sculpture by Joan Brossa which spells out the name Barcino.

The section of wall begins in Carrer de la Tapineria.
