Barcelona.

Barcelona is located on the Northeast coast of the Iberian Peninsula, facing the Mediterranean Sea, on a plateau approximately 5 km (3 mi) wide limited by the mountain range of Collserola, the Llobregat river to the south-west and the Besòs river to the north. This plateau has 170 km² (66 sq mi), of which 101 km² (38.9 sq mi) are occupied by the city itself. It is 160 km (100 mi) south of the Pyrenees and the Catalonian border with France.

Collserola, part of the coastal mountain range, shelters the city to the north-west. Its highest point, the peak of Tibidabo, 512 m (1,680 ft) high, offers striking views over the city and is topped by the 288.4 m (946.2 ft) Torre de Collserola, a telecommunications tower that is visible from most of the city. Barcelona is peppered with small hills, most of them urbanized and that gave their name to the neighbourhoods built upon them, such as Carmel (267 m), Putxet (181 m) and Rovira (261 m). The escarpment of Montjuïc (173 m), situated to the southeast, overlooks the harbour and is topped by Montjuïc castle, a fortress built in the 17–18th centuries to control the city as a replacement for the Ciutadella. Today, the fortress is a museum and Montjuic is home to several sporting and cultural venues, as well as Barcelona's biggest park and gardens.

The city borders are the municipalities of Santa Coloma de Gramenet and Sant Adrià de Besòs to the north; L'Hospitalet de Llobregat and Esplugues de Llobregat to the south; the Mediterranean Sea to the east; and Montcada i Reixac and Sant Cugat del Vallès to the west.

Barcelona contains 68 municipal parks, divided into 12 historic parks, 5 thematic (botanical) parks, 45 urban parks and 6 forest parks. They range from vest-pocket parks to large recreation areas. The parks cover 10% of the city (549.7 ha/1,358.3 acres), growing about 10 ha (25 acres) per year, with a proportion of 18.1 square metres (195 sq ft) of park area per inhabitant.

Of Barcelona's parks, Montjuïc is the largest, with 203 ha located on the mountain of the same name. It is followed by Ciutadella Park (situated in the place of the old military citadel and which houses the Parliament building, the zoo and several museums; 31 ha/76.6 acres including the zoo), the Guinardó Park (19 ha/47.0 acres), Park Güell (designed by Antoni Gaudí; 17.2 ha/42.5 acres), Oreneta Castle Park (also 17.2 ha/42.5 acres), Diagonal Mar Park (13.3 ha/32.9 acres, inaugurated in 2002), Nou Barris Central Park (13.2 ha/32.6 acres), Can Dragó Sports Park and Poblenou Park (both 11.9 ha/29.4 acres) and the Labyrinth Park (9.10 ha/22.5 acres), named after the garden maze it contains. A part of the Collserolla Park is also within the city limits.

Barcelona has seven beaches, totalling 4.5 km (2.8 mi) of coastline. Sant Sebastià and Barceloneta beaches, both 1,100 m (3,610 ft) in length, are the largest, oldest and the most frequented beaches in Barcelona. The Olympic port separates them from the other city beaches: Nova Icària, Bogatell, Mar Bella, Nova Mar Bella and Llevant. These beaches (ranging from 400 to 640 m/1,300 to 2,100 ft) were opened as a result of the city restructuring to host the 1992 Summer Olympics, when a great number of industrial buildings were demolished. At present, the beach sand is replenished from quarries given that storms regularly remove large quantities of material. Greenpeace has criticized the beaches as environmentally unsustainable and as prejudicial to sea bed flora and fauna. The 2004 Universal Forum of Cultures left the city a large concrete bathing zone sited near the municipal incinerator and a sewage treatment plant.

Barcelona has many venues for live music and theatre, including the world-renowned Gran Teatre del Liceu opera theatre, the Teatre Nacional de Catalunya, the Teatre Lliure and the Palau de la Música Catalana concert hall. Barcelona also is home to the Sónar Music Festival which takes place around June every year, and to the Barcelona and Catalonia National Symphonic Orchestra (Orquestra Simfònica de Barcelona i Nacional de Catalunya, usually known as OBC) is the largest symphonic orchestra in Catalonia. In 1999, the OBC inaugurated its new venue in the brand-new Auditorium (l'Auditori). It performs around 75 concerts per season and its current director is Eiji Oue. It has a thriving alternative music scene, with groups such as The Pinker Tones receiving international attention.
