Castillo de San Marcial de Rubicón de Femés

Perched dramatically on a rocky promontory overlooking the strait between Lanzarote and Fuerteventura, the Castle of San Marcial de Rubicón—also called Torre del Águila or Tower of the Eagle—stands as a weathered sentinel from an era when Berber, English, and French pirates terrorized these shores. This 18th-century fortification, complete with a small drawbridge and volcanic stone walls, was part of a defensive network that once protected the island's vulnerable southern coast.

While the interior remains closed to visitors, the surrounding landscape more than compensates. The clifftop walk leading to the castle offers breathtaking rewards, especially at sunset when golden light floods the nearby Papagayo Beaches and Fuerteventura's silhouette sharpens against the horizon. From this strategic vantage point, it becomes clear why this spot was chosen to guard the Rubicón Marina below.

Open around the clock, this historic site attracts photographers and walkers who appreciate uncrowded heritage spots with genuine character. The accessible path and stunning coastal panoramas make it a favorite among those seeking authentic island history beyond the typical tourist circuit.
