One of the most visited sights in Catalonia is the monastery at Montserrat, 35 miles (56km) northwest of Barcelona. The monastery is surrounded by strange rocky crags and caves, and was founded in 1025 to celebrate local visions of the Virgin Mary. It has become one of the most important pilgrimage sites in Spain, sitting atop a 4,000-foot (1,200m) high mountain and housing about 80 monks. Its main claim to fame is a 12th century Romanesque wooden sculpture of a black Virgin Mary known as La Moreneta, which thousands come here to see and touch. The monastery on its mountain perch is reached by cable car.

Transport: Train from Espanya station (one hour)

Admission: Entry to the monastery is free, but the funicular ride to the Holy Grotto is €6
