Montserrat is a mountain near Barcelona, in Catalonia. It is the site of a Benedictine abbey, Santa Maria de Montserrat, which hosts the Virgin of Montserrat sanctuary. Montserrat is a multi-peaked mountain range near Barcelona, in Catalonia, Spain. It is part of the Catalan Pre-Coastal Range. The main peaks are Sant Jeroni (1,236 m), Montgrós (1,120 m) and Miranda de les Agulles (903 m). It is well known as the site of the Benedictine abbey, Santa Maria de Montserrat, which hosts the Virgin of Montserrat sanctuary. Montserrat literally means "saw (serrated, like the common handsaw) mountain" in Catalan. It describes its peculiar aspect with multitude of rock formations which are visible from a great distance. The mountain is composed of strikingly pink conglomerate, a form of sedimentary rock. Montserrat was designated as a National Park in 1987. On this mountain we will have access to the Monastery of Montserrat which houses the virgin that gives its name to the monastery, although it is also known as La Moreneta
