Roman Walls, Barcelona

The Roman Walls were once completely surrounded by the Barcino settlement. They were nine meters (30 feet) high and 3.5 meters (11.5 feet) thick, and stretched for 1270 meters (4170 feet). Most of the walls have disappeared or were used as the foundations for later buildings. The best preserved parts can be seen on Plaça de Ramón Berenguer el Gran (next to Via Laietana), on the Avenida de la Catedral, the Pia Almoina, Plaça dels Traginers, Carrer del Correu Vell and on Carrer Regomir, which lead to the Roman port.
