Founded in 1168, the building of the Santa María de Gradefes Church, according to an engraving on the northern lower wall, began on March 1st, 1177 under the patronage of the woman who became its Abbess -Teresa Pérez, widow of García Pérez, a knight of Alfonso VII. The first community was made up of Cistercian nuns who came from the monastery of Tulebras, Navarra. It became an important and privileged female monastery.
It is the only example in Spain of a female monastery having an ambulatory. In the church are the tombs with statues of the founding couple, a polychromatic work from the late 13th century. Kept in the monastery rooms are the polychromatic wooden carvings of a 12th century Virgin and a Gothic Christ, formerly part of a Calvary from the 14th century.

In monastic dependencies are kept polychrome carvings of a Virgin of the XII century and a Gothic Christ which was part of a Calvary of the XIV. Garments and shoes belonging to the founder are also kept.
References:The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
