Tower of el Clot dels Frares Monument · Sant Pere de Ribes, Garraf, Barcelona The Clot dels Frares complex is a building declared a Bien Cultural de Interés Nacional (Catalonia's highest level of heritage protection) in the municipality of Sant Pere de Ribes (Garraf), on the former grounds of the Autodrome. It consists of a farmhouse with ground floor, upper floor and attic under a four-pitched roof, and a defensive tower with a square floor plan, linked to it by a bridge, which preserves remains of Baroque sgraffito. The place may correspond to the old lordship of Vila-Rúbia or Vila-Roja, extinguished in 1410; the name Clot dels Frares is linked to a community of Hieronymites established in 1413, or to the fact that in the early 18th century the estate belonged to the Society of Jesus. The farmhouse, from the 17th century, served as the Royal Pavilion during the years of the Autodrome and is today a summer residence.
