Monastery of San Pedro de Cervatos

The first documented reference to this house is the granting of a legal normative (fuero) by Sancho García, Count of Castile, in the year 999. Later, the monastery of Cervatos received donations, privileges, and confirmations of the aforementioned fuero, making it a very influential religious and power center. During the 12th century, the current church was built, and in 1186, the monarchy, which had been the owner and benefactor of the house until that time, handed it over to the diocese of Burgos. In fact, it was an exchange with Santa Eufemia de Cozuelos (Palencia).

A Romanesque church from the 12th century is still preserved, with a single nave, although it has been modified over time, with structures added to the north side. It has a notable Romanesque portal, located in a more advanced position than the facade, with its own eave supported by modillions. The portal has three columns on each side, a tympanum, and archivolts, all with profuse decoration. The modillions on the eaves of the portal and those on the church itself feature abundant and varied sculptural decoration.
