The monastery was originally founded by Dona Mor Dias in 1283. In the 14th century, Clement V granted permission to Dona Isabel of Aragon to found a new monastery, which was established on the same site, with the renovation and expansion of the old buildings.

We highlight the Baroque interventions that reveal a period of space revitalization in the 17th and 18th centuries.

Dating from 1660, deserve reference the blue tiles from the 17th century, existing in the tops of the old dorms.
