Carteia (Ancient Greek: Καρτηίᾳ) was a Phoenician and Roman town at the head of the Bay of Gibraltar in Spain. It was established at the most northerly point of the bay, next to the town of San Roque, about halfway between the modern cities of Algeciras and Gibraltar, overlooking the sea on elevated ground at the confluence of two rivers, nowadays called Guadarranque and Cachon.According to Strabo, it was founded around 940 BC as the trading settlement of Kʿrt (meaning "city" in the Phoenician language; compare Carthage and Cartagena). The area had much to offer a trader; the hinterland behind Carteia, in the modern south of Andalusia, was rich in wood, cereals, oranges, lemons, lead, iron, copper and silver. Dyes were another much sought-after commodity, especially those from the murex shellfish, used to make the prized Tyrian purple. Strabo and Pomponius Mela, mention that some believe that Carteia used to be the Tartessos. Pliny the Elder writes that Carteia was called by the Greeks Tartessos.The town's strategic location meant that it played a significant role in the wars between Carthage and the Roman Republic in the 2nd and 3rd centuries BC. It may have been the site of Hamilcar's landing with his army and elephants in 237 BC, and in 206 BC the Carthaginian admiral Adherbal retreated there with the remnants of his fleet after being defeated by Gaius Laelius in the Battle of Carteia. Around 190 BC, the town was captured by the Romans.

The Gibraltar-San Roque Refinery (Spanish: Refinería de Gibraltar-San Roque) is an oil refinery owned by CEPSA located on the north shore of the Bay of Gibraltar, in Guadarranque Industrial Estate, between Puente Mayorga and the Guadarranque river, in the municipality of San Roque, Cadiz, Spain. It is located next to the Los Barrios Power Plant, which is a coal fueled power station. It is the largest refinery in the Iberian Peninsula, with a crude oil daily processing capacity of 240,000 barrels per day. The refinery occupies 150 acres and has a refining capacity of 12 million tons per year, making it the largest Spanish refinery. The Spanish Government has been accused of having built the refinery deliberately in an effort to negatively affect the British Overseas Territory of Gibraltar, although pollution is indiscriminate and it also affects a large Spanish population in southern Spain. The results of local air samples by both the Gibraltar and Spanish NGOs and environmental groups are regularly reported to the relevant European Union institutions. Apart from imposing fines on the wealthy CEPSA conglomerate, no other real action is taken. As of 2018 work began on using Detal technology which will produce linear alkylbenzene, work will take around two years to complete.
