Convent of Miralles Monument · Castellví de Rosanes, Baix Llobregat, Barcelona The Convent de Miralles, declared a Bien Cultural de Interés Nacional (Catalonia's highest level of heritage protection), had as its first building a square-plan fortress of the 9th or 10th century built on a Roman base; on top of it a Gothic casal (manor house) was raised in the 13th and 14th centuries. It belonged in 1210 to Guerau Alemany de Cervelló and, at the end of that century, to Bernat de Miralles, who died in 1311; at the start of the 15th century it belonged to Guillem Codorniu, of Gelida. In 1410 the Barcelona merchant Bertran Nicolau founded an Augustinian monastery here, and in 1414 two friars from the Barcelona convent bought the Miralles estate (cuadra) and turned the old fortified casal into the Casa de Déu de Miralles, building and painting a chapel at that time. In the 18th century that chapel became too small and the current main church was built. Photo: Josep Salvany i Blanch (Public domain) What to see and do in Castellví de Rosanes
