Mazarrón

The Bay of Mazarrón is sheltered by the foothills of the Sierra de la Almenara, a mining area since the Carthaginian era. The Bay has over 35 km of beaches, unspoiled coves and rocky sea beds. The beach at Bolnuevo is of coarse grit, as are most beaches along this part of the coast.

A military fortification built in the 1930s is a tourist attraction, and is located on the old road between Mazarrón and Cartagena, just outside the municipality.

The 'Torre de los Caballos' tower was built to defend the town from pirate raids that occurred from the mid-16th to the early 18th centuries.

The economic development of the early 20th century led to the construction of buildings in the style known as Murcian Modernism, including the Mazarrón Town Hall and the former Cultural Athenaeum.
