In about 15 BCE the Romans founded Barcelona, named Barcino. Although the capital of this area in the Empire was Tarragona (Roman Tarraco), Barcelona did have a harbor. Like most Roman new towns, it was laid out in a grid and fortified. Some of the original Roman walls are in Barcelona's Old Town (the Barri Gótic); here they are incorporated into the walls of the chapel of Santa Ągata, part of the former royal palace complex.
