Castillo de Cortegana is the defining feature of the village skyline, a compact medieval fortress on a rocky outcrop above the rooftops. Originally constructed in 1253 and significantly enlarged in 1293 under Sancho IV, the castle has been substantially restored and its interior fitted with suits of armour, period furniture, and a small exhibit on the sierra's history.
The views from the walls are the best reason to make the climb — the oak and chestnut hills of the Sierra de Aracena roll away in every direction, and on clear days the white villages of Almonaster la Real and Aracena are visible in the middle distance. Within the castle's outer walls stands the 13th-century hermitage of Nuestra Señora de la Piedad. Opening hours are limited (closed Mondays; typically 11:00–14:00 and 16:00–18:00). In August, the castle hosts a four-day medieval festival.
