The earliest known reference to this fortification dates from the year 940. Today, medieval remains can still be seen, including the base of a circular tower around 3.5 metres in diameter, built with squared stone blocks and lime mortar, several walls, and a cistern covered with a barrel vault and sealed with a large stone slab. In the early 20th century, Josep M. Pericas carried out the first excavation, and in 1972 the base of the round tower and the foundations of the access wall were unearthed. A later survey revealed an arrowhead, fragments of medieval pottery and an ancient strategic path, partially carved into the rock, which provided access to the site.
In 2019, the Fundació l’Esquerda conducted an archaeological excavation that documented the full layout of the circular tower and a northern enclosing wall. In 2021, the documented structures were consolidated and restored.
The castle, located on a hilltop, defended the territory that now forms the municipality of l’Esquirol. It was the ancestral home of the Cabrera family, one of the most influential feudal lineages in medieval Catalunya. Gausfred de Cabrera was the first recorded lord of the castle in the early 11th century. The castle remained part of the Viscountcy of Cabrera until the abolition of feudal lordships in the 19th century.
