Introduction
The castle is first mentioned in documents from the year 957, although later records indicate that it already existed during the time of Count Sunyer of Barcelona. In medieval times, it was the seat of a territorial jurisdiction, the territory of the castle of Eramprunyà, which controlled what are now the municipalities of Gavà, Begues, Castelldefels, Sant Climent de Llobregat and Viladecans.
The castle stands at an altitude of 400 m and is built using the characteristic reddish stone of the area. Its layout followed an almost rectangular plan and was partially surrounded by a double line of walls: the upper or sovereign enclosure and the lower or outer enclosure.
You first reach the lower enclosure, where you will find the castle chapel, formerly the parish church of Sant Miquel d’Eramprunyà, in Romanesque style although heavily modified; the cemetery, with anthropomorphic graves oriented east to west; and a rectangular cistern built in the 14th–15th centuries.
Access to the upper enclosure is via a wooden footbridge replacing the original stone bridge. The entire upper enclosure is surrounded by walls. It includes the gateway or guardhouse facing the valley, with walls 90 cm thick; a Romanesque arrow slit with a remaining arch 1.5 m wide; a hall with round arches; and remains of a cistern and two chambers.
