In order to control the moves of the counts of Empuriés, the court of Barcelona commanded Bernat de Llabià, the governor of the Royal town of Torroella de Montgrí, to supervise the building of a fortress on top of the Montgrí Massif.

The GR 92 long distance footpath, which roughly follows the length of the Mediterranean coast of Spain, passes the castle on its stage between Sant Martí d'Empúries and Torroella de Montgrí.

The only parts erected were the perimeter walls, forming a square of 31 m (102 ft)31m along each side, and the four round towers at its corners.

However the interior surfaces of the wall retain certain elements (toothing stones and springings for arches and vaults) which enable us to visualize the structure that these buildings were to have.

Outside the castle, the former quarries can be seen, as well as the remains of a wall in the south face and a large cistern on the northern slope of the mountains.
