La Bestorre Monument · Monistrol de Montserrat, Bages, Barcelona La Bestorre, or tower of Monistrol, is a circular watchtower situated on the hill of the same name, in Monistrol de Montserrat; it is reached by a path leading off the road that climbs to the monastery of Montserrat, shortly before kilometre 5. It probably served to protect the parish district and, from the late 12th century, the old medieval bridge over the Llobregat, on the site of the present one; however, an archaeological survey in 2002 cast doubt on this medieval dating. During the War of the Spanish Succession, the abbot of Montserrat, Manuel Marrón, had it blown up for fear of the supporters of Archduke Charles. A fragment of wall about 3.90 metres high survives, of well-cut ashlar, with an interior diameter of 4.80 metres. Photo: Enric (CC BY-SA 3.0) What to see and do in Monistrol de Montserrat
