Legend holds that two local heroes, Guillem Cabrit and Guillem Bassa, were burnt at the stake by King Alfonso III of Aragon for refusing to surrender the castle.
The mountain's distinct flat-topped appearance is the result of geological erosion known as a mesa.
The site was historically used as a signaling station for communication across the island using fire and smoke.
Archaeological excavations have uncovered fragments of Islamic-era ceramics dating to the 10th century.
The refuge on the summit is housed in a renovated part of the old garrison buildings.
The cisterns found within the walls were engineered to collect rainwater to sustain the garrison during prolonged sieges.
Castell d'Alaró is a historic rock-cut fortress located on the summit of Puig d'Alaró in the Serra de Tramuntana mountains. The site sits at an elevation of 822 meters, providing strategic views across the central plains of Mallorca toward the bay of Palma. The current stone fortifications date primarily from the 15th century, though archaeological evidence confirms the site was occupied during the Bronze Age and the Islamic period. Notable features include the remnants of the main entrance gate, the parade ground, and a small chapel dedicated to Our Lady of the Castle. The site played a critical role during the conquest of Mallorca in 1229, serving as a final refuge for the island's defenders. Access is achieved exclusively via a steep, unpaved hiking trail that takes approximately one hour to ascend from the base. A mountain refuge operates on-site, offering basic lodging and food services for hikers. The structure remains under the protection of the Council of Mallorca as an Asset of Cultural Interest.
The edge of the northern defensive wall looking toward the Tramuntana mountain range.
Wear sturdy hiking boots, as the trail consists of loose, uneven limestone scree.
Carry at least 1.5 liters of water per person, as there are no natural water sources on the ascent.
Bring a windbreaker even in summer, as temperatures drop significantly at the summit.
Do not attempt the climb in flip-flops or open-toed sandals due to the sharp rock terrain.
The refuge may occasionally close for private events; check local updates before planning a stay.
Respect the mountain refuge by carrying out all trash; maintain a quiet demeanor near the chapel.
