Castle of Eramprunyà Monument · Gavà, Baix Llobregat, Barcelona The castle of Eramprunyà stands atop a mountain between cliffs, overlooking the Llobregat delta and the Garraf, in the municipality of Gavà. First recorded in 957, it was the seat of an extensive medieval district that came to control Gavà, Begues, Castelldefels, Sant Climent de Llobregat, Viladecans and part of Sant Boi, and belonged to the counts of Barcelona before passing in the 14th century to the March family, knights and poets. It was heavily damaged during the Remença peasant wars of the 15th century. The complex consists of three fortified enclosures: the upper one, with the ruins of the Gothic castle-palace; the middle one, with the Romanesque hermitage of Sant Miquel d'Eramprunyà, from the 12th and 16th centuries; and the outer one, where a good part of the old wall is preserved.
