Montserrat is a mountain near Barcelona, in Catalonia, in Spain. It is the site of a Benedictine abbey, Santa María de Montserrat, which hosts the Virgin of Montserrat sanctuary and which is identified by some  with the location of the Holy Grail in Arthurian myth.
The name “Montserrat” literally means “jagged mountain” and is used because of the peculiar aspect of the rock formation, which is visible from a great distance. It is composed of strikingly pink conglomerate, a form of sedimentary rock. It is very popular with climbers.
