The Gothic Quarteris the centre of the old city of Barcelona. It stretches from La Rambla to Via Laietana, and from the Mediterranean seafront to Ronda de Sant Pere. It is a part of Ciutat Vella district. The quarter was built primarily in the late 19th and early 20th century, though several buildings date from medieval times. Remains of the squared Roman Wall can be seen around Tapineria and Sots-Tinent Navarro to the north, Avinguda de la Catedral and Plaça Nova to the west and Carrer de la Palla to the south. El Call, the medieval Jewish quarter, is located within this area too. The Barri Gòtic retains a labyrinthine street plan, with many small streets opening out into squares. Most of the quarter is closed to regular traffic although open to service vehicles and taxis.
