Santa Maria de Mur, Romanesque monastery in Castell de Mur, Spain.

Santa Maria de Mur is a Romanesque monastery situated at high elevation featuring three barrel-vaulted naves supported by stone pillars. The building complex includes defensive walls that transformed it into a fortified religious structure.

The monastery was established in the late 11th century and received ecclesiastical approval shortly after its founding. This early authorization allowed it to develop into an important religious center of the region.

The monastery was home to a community of Augustinian canons installed by Count Pere Ramon around 1100, who placed it directly under the Holy See. At its height about ten canons lived here; by the end only three to five remained. The 13th-century Sant Crist image was burned in 1936 and later replaced by a replica.

The site is located in a remote area that requires preparation before visiting. Access can be challenging depending on season and weather, so checking conditions beforehand is advisable.

The central apse murals were removed by the strappo technique in 1919 and sold to the antiquarian Ignacio Pollak despite protests from the Junta de Museus de Catalunya. They are now in the Museum of Fine Arts, Boston, while the south apsidiole paintings are in the Museu Nacional d'Art de Catalunya in Barcelona. Small, darkened fragments remain in situ.
