The Gothic Quarter (Catalan: Barri Gòtic, Spanish: Barrio Gótico) is the historic centre of the old city of Barcelona. The quarter encompasses the oldest parts of the city of Barcelona, and includes the remains of the city's Roman wall and several notable medieval landmarks.
The Gothic Quarter retains a labyrinthine street plan, with many small streets opening out into squares. Most of the quarter is closed to regular traffic but open to service vehicles and taxis.
El Raval is a neighborhood in the Ciutat Vella district of Barcelona, situated next to the Gothic Quarter, it currently has a very diverse immigrant community and is home to many bars, restaurants and night spots.
La Ribera (The Shore) is one of the areas of the old quarter of Barcelona.
Many of the buildings date from late Medieval times. It was a well-to-do quarter during the 13th–15th centuries, when it really was by the sea shore.
Someone may worry about the public order of Barcelona, but Choumeizai doesn't have any problem even though he walks around by himself. Anyway, if the street is very crowded, be careful of your personal belongings.
