Geography
Barcelona location was 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.[11] This plateau has 170 km² (66 sq mi),[11] of which 101 km² (38.9 sq mi)[12] 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[13] and is topped by the 288.4 m (946.2 ft) Torre de Collserola, a tower for telecommunications purpose 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 Montjuic (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 Montjuïc 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.
