Mazarrón is set in a wide bay that opens up into the Mediterranean and has a coastline of 35 km. It has two main urban centres, the port area “Puerto de Mazarrón" and the town centre which is located 5km inland from the coast.
Since its origins, the name of Mazarrón has been linked to the mining wealth of its mountain ranges, which are rich in lead, zinc, silver, iron, aluminium and red ochre. In Phoenician, Punic and Roman times, great work was carried out in these mines, leaving behind an abundance of archaeological remains. The Arabs also settled in the area, attracted by its mineral wealth. After the Christian Reconquest, the place known as Casas de los Alumbres de Almazarrón was formed as a consequence of the mines that were opened in the 15th century. Its strategic position turned it into a bastion of defence for the neighbouring Cities of Lorca and Cartagena, evidence of which can be seen in the numerous defence towers dotted along the clifftops that were built to stop the Saracen advance from Africa. Mazarrón became very important at the end of the 19th century and beginning of the 20th, during which time iron and galenite were mined. Once the wealth of the mines had been exhausted, Mazarrón turned to a tourism and agriculture, and at the same time, promoted its seafaring and fishing tradition. This can be seen in the port, where there is a fish market and numerous shallow water fishing boats.
Mazarrón´s main tourist areas and beaches include Bolnuevo and Puerto de Mazaónrr to the South and Isla Plana and La Azohia to North. Whilst it has a vibrant and modern centre from a real estate perspective it remains relatively under developed although new villas and apartments are being built with further planned in the coming years.
