Rubia Tower, locally known as Torre Rubia, lies west of the town of Molinos Marfagones in the province of Murcia in Spain.
In the 16th and 17th century the area of Cartagena was prone to attacks by Barbary pirates. Several rural watch towers were built which both served as a place of refuge for the local farmers and as a signal tower.
The Rubia Tower was built in the 16th century, during the reign of Philip II of Spain. It has a square plan.
Rubia Tower is part of a residence and thus private property. It can not be visited. It can however easily be viewed from the public road. Moro Tower is nearby.
