Tower of la Serra Monument · Sant Pere de Ribes, Garraf, Barcelona The Torre de la Serra crowns the south-east corner of the la Serra farmhouse, on a hill west of the municipality of Sant Pere de Ribes. It is a defensive tower with a quadrangular floor plan, joined to the rest of the farmhouse, among whose outbuildings the wine cellar stands out. The complex, with ground floor and upper floor under a tiled roof, has a façade with a voussoired flat-arched doorway and several rectangular openings. The name Sasserra appears linked to a 12th-century property and to a family settled there in the late 13th century, but references to the present building begin in the 16th century, when the property belonged to the Roig de la Serra family, who added the tower when they enlarged the house; the Roig family has remained the owner to this day. An inscription from 1806 records a later extension. Photo: Deosringas (CC BY-SA 3.0 es) What to see and do in Sant Pere de Ribes
