Torre Río Real

Marbella, Spain, Spain

---

Torre Río Real in Marbella, Spain, is a 16th-century coastal watchtower constructed in 1575 as part of Andalusia's defensive network against Barbary pirate raids, standing 10.85 meters tall with a 22-meter circumference on a square base beside the Mediterranean Expressway.

Built over an earlier Moorish structure during King Philip II's program to protect depopulated coasts post-Reconquista, it features machicolations for dropping boiling oil on attackers and served for signaling via smoke or fire to neighboring towers until repurposed as a Guardia Civil post against smuggling into the 20th century. 

Declared a Bien de Interés Cultural, this well-preserved beacon now symbolizes Marbella's transition from frontier outpost to luxury resort, offering sea views amid the upscale Río Real neighborhood near the historic golf club.
