Castell de Miralpeix is a ruined fortress in Sitges, Barcelona, dating from at least 1057 when Bishop Guislabert granted the tower to Arnau d'Arloví with the condition of rebuilding and resettling it. The remains occupy approximately 275 square meters with a rectangular layout containing two rooms, a quadrangular tower, and a cistern. Located at the western extreme of Sitges' territory near Sant Pere de Ribes, the castle appears to have been destroyed in 1190 during a conflict between local nobility. The site remains an important archaeological record of medieval Catalan fortifications.
