It is an architectural work from the end of the 15th Century, under the guidance of Fray Alonso de Burgos, confessor of the Catholic Monarchs and Bishop of Palencia.

Its monumental façade replete with decorative and sculptured elements attributed to Gil de Silóe is worth noting. With Fray Alonso before the Pope in the tympanum and St. Dominic and St. Paul at the sides.

The buttresses are decorated with warriors. There are also angels with the armorial bearings of the founder. In the centre piece there is a pomegranate tree sheltering the arms of the Catholic Monarchs with a pomegranate in the top representing their conquer (so it is dated after 1492).

The design of the chapel, where the bishop is buried, is attributed to the architects Juan Guas and Juan de Talavera, starting in 1484. In 1499 a sacristy by Simón de Colonia was attached to it. Now it is state property and houses since 1933 the National Scultpture Museum.
