Llobregat in the context of "Martorell"

Barcelona (/ˌbɑːrsəˈloʊnə/ BAR-sə-LOH-nə; Catalan: [bəɾsəˈlonə] ; Spanish: [baɾθeˈlona] ) is a city on the northeastern coast of Spain. It is the capital and largest city of the autonomous community of Catalonia, as well as the second-most populous municipality of Spain. With a population of 1.7 million within city limits, its urban area extends to numerous neighbouring municipalities within the province of Barcelona and is home to around 5.7 million people, making it the fifth most populous urban area of the European Union after Paris, the Ruhr area, Madrid and Milan. It is one of the largest metropolises on the Mediterranean Sea, located on the coast between the mouths of the rivers Llobregat and Besòs, bounded to the west by the Serra de Collserola mountain range.

According to tradition, Barcelona was founded by either the Phoenicians or the Carthaginians, who had trading posts along the Catalonian coast. In the Middle Ages, Barcelona became the capital of the County of Barcelona. After joining with the Kingdom of Aragon to form the composite monarchy of the Crown of Aragon, Barcelona, which continued to be the capital of the Principality of Catalonia, became the most important city in the Crown of Aragon and its main economic and administrative centre, only to be overtaken by Valencia, wrested from Moorish control by the Catalans, shortly before the dynastic union between the Crown of Castile and the Crown of Aragon in 1516. Barcelona became the centre of Catalan separatism, briefly becoming part of France during the 17th century Reapers' War and again in 1812 until 1814 under Napoleon. Experiencing industrialization and several workers movements during the 19th and early 20th century, it became the capital of autonomous Catalonia in 1931 and it was the epicenter of the revolution experienced by Catalonia during the Spanish Revolution of 1936, until its capture by the fascists in 1939. After the Spanish transition to democracy in the 1970s, Barcelona once again became the capital of an autonomous Catalonia.

The Serra de Collserola (Catalan pronunciation: [ˈsɛrə ðə ˌkɔʎsəˈɾɔlə]), or simply Collserola, is a mountain range between the rivers Besòs and Llobregat. It is part of the Catalan Coastal Range.

These mountains separate Barcelona from the Vallès plain and their tallest peak is the Tibidabo, at 512 m. Other main summits are: Turó del Puig, Puig d'Olorda, Turó de Valldaura, Turó de la Magarola, Puig d'Ossa, and Puig Madrona. The valleys of the Llobregat and Besós Rivers, the plain of Barcelona, and the Vallès basin, mark the geographical boundaries of the Collserola massif.

Central Catalonia (Catalan: Catalunya Central; IPA: [kə.təˈɫu.ɲə sənˈtɾaɫ]), also known as Comarques Centrals, is one of the nine regions (vegueries) of Catalonia.

It had 412,033 inhabitants in 2022. Located around the upper and middle sections of the Llobregat and Ter rivers, it includes the counties of Bages, Berguedà, Lluçanès, Moianès, Osona and Solsonès. It borders to the north-west with Alt Pirineu, to the west with Ponent, to the south with Penedès, to the south-east with Barcelona and to the north and north-east with Girona.

The Pont del Diable (Spanish: Puente del Diablo, English: Devil's bridge), also known as Sant Bartomeu Bridge, is a medieval bridge crossing the river Llobregat and straddling the municipalities of Martorell and Castellbisbal in Catalonia, Spain. The bridge is restricted to pedestrians.

The present bridge, featuring a large pointed arch, is a 1965 reconstruction of the gothic bridge built in 1283 on Roman foundations. The main clear span is 37.3 metres (122 ft) with a stone chapel on top. A secondary arch has a span of 19.1 metres (63 ft). The bridge was destroyed in 1939 during the Spanish Civil War by retreating Republican troops, but rebuilt in 1965 in a form generally similar to the gothic structure. It is now surrounded on three sides by road flyovers and railway lines.

Cardona (Catalan pronunciation: [kəɾˈðonə]) is a town in the Spanish region of Catalonia, in the province of Barcelona; about 90 km (56 mi) northwest of the city of Barcelona, on a hill almost surrounded by the river Cardener, a branch of the Llobregat. To the east of the town, the river has been diverted through a tunnel has been dug through a spur, leaving a loop of dry river bed near the saltmine.

Near the town is an extensive deposit of rock salt. The salt forms a mountain mass (called Muntanya de Sal) covered by a thick bed of a reddish-brown clay, and apparently resting on a yellowish-grey sandstone. It is generally more or less translucent, and large masses of it are quite transparent. The hill has been worked like a mine since Roman times; pieces cut from it have been carved by artists in Cardona into images, crucifixes and many articles of an ornamental kind.
