Santa Elena tower, Coastal watchtower in La Azohía, Cartagena, Spain
Santa Elena Tower is a coastal watchtower built on a rocky elevation overlooking the Mediterranean Sea, featuring a rectangular base and positioned for clear maritime observation. The structure rises above the surrounding landscape and commands sightlines across the water in all directions.
The tower was built between 1556 and 1598 under the direction of Giovanni Battista Antonelli as part of a defense system against Barbary pirates threatening the Spanish Mediterranean coast. It emerged during a period when coastal fortifications were necessary to protect merchant ships and settlements.
The tower demonstrates how coastal residents defended themselves against pirates through a chain of watchtowers connected by smoke and fire signals. This communication system linked multiple structures into a coordinated network.
The tower sits on Carretera Isla Plana in La Azohía and remains accessible for exterior viewing and photography throughout the year. The cliffside location means visitors should wear sturdy footwear and take care in windy conditions.
The tower transmitted warnings through smoke signals by day and fire signals by night to neighboring watchtowers. This simple system allowed several towers to activate an alarm chain within minutes without requiring messengers to travel between them.
