Foundation Information

Founded by Teoda and Argontí, who may have been ancestors of the Alfonsine line that came to rule the kingdom of Asturias

First Members

Of the 36 original members (all female), about half of the names were Visigothic, and half were Latinate.

Notable Heads

Dates for the following abbesses are based on documents in which they appear, and thus probably do not reflect each abbess' full tenure: Ailón (941-966); Fronilde (977-981); Justa (997-999); Fronilde (1030); Eilo (1039); Urraca Alfonsa, daughter of Alfonzo Diaz (1048-dissolution of the double community)

Population Counts

At foundation: 36 nuns + Abbess Ailón.

Incorporated Communities

S. Julian, in 1045

Incorporated By

Some time between 1075 and 1079, S. María ceased to be a double monastery. At this point, the nuns were absorbed into the community of S. Pedro de las Dueñas, and Urraca became abbess there. The male community became a dependency of the community of Sahagún shortly thereafter.


Founders, members of the Alfonsine line (many of whom served as abbesses).

Secular Political Affiliations

Considered a "proprietary monastery" during the 10th c., more independant during the 11th.

Social Characteristics

Mixed, although many sons and daughters of the nobility were members.


Included the village of Piasca, the church of s. Eulalia, and numerous properties near Piasca, as well as the more distant community of S. Julian and its properties (after 1045). Also controlled numerous churches, includeing Santiago y Santa María de Perrozo, San Julián de Plano, and San Pelayo and San Miguel de Luriezo.

Miscellaneous Information

Although it was founded as a double monastery, women predominated at the beginning. They may have been the only original members, but there were men at the community at least as early as 945. The double community was under the supervision of an abbess during the 10th and early 11th centuries, but by the mid-11th century was usually ruled by an abbot-abbess pair, although the woman occasionally lacked the title of abbess.
