Castell del Rei, Rock castle in Pollensa, Spain
Castell del Rei is a rock castle perched on a crag in the Sierra de Tramontana at roughly 492 meters elevation. The structure consists of stone walls and ruins that overlook the valleys and terrain of northern Mallorca.
The site functioned as a Roman fortification and later became one of the final Muslim strongholds on the island. It fell to King James I of Aragon in 1229 during the Christian conquest of Mallorca.
The castle received official recognition as a Cultural Heritage Site of Spain in November 1993, marking its importance in the region's architectural legacy.
Visiting requires permission to cross the private Valle Ternelles estate where the castle sits. Local adventure companies organize guided hikes that handle access logistics and provide safe routing through the terrain.
From this location, views spread across Pollença, Alcudia, and the surrounding bay in multiple directions. The vantage point reveals much of the northern coastline and offers an unusual perspective on how the island's geography connects.
