The spring inside the Spanish watchtower

The Torre de Cope, nicknamed Santo Cristo, stands in Altos de Cabo Cope, a park on Murcia's northeastern coast. Towns here suffered frequent attacks from North African pirates and raiders. In 1539, King Carlos I commanded the construction of the tower within the town of Águilas in response to this threat. Later in 1568, King Felipe II asked the military commander Vespasiano I Gonzaga to inspect and design fortifications on the region's coasts. Gonzaga, accompanied by Juan Bautista Antonelli, oversaw the 1574 completion of the Torre de Cope. Three to four guards defended it from the tower. Construction of the tower began in 1539 and was completed in 1574. Restoration work in 1990-1991 involved the tower and the Torre de Santa Isabel, part of an agreement between the Region of Murcia and the INEM. The budget for both totalled over 6.2 million pesetas.
