The founding of the monastery of Santa Maria de Mur in the XII century spelled the end of the nearby castle’s bellicose existence. As a result the Castle of Mur is an almost unique example of unmodified Romanesque military architecture. The restored cloister is one of the centrepieces of the complex, which, as well as being open to the public, hosts an annual Aplec, or get together, on the first Sunday in May.
