This palace of an irregular floor layout was built at the end of the 15th century according to the date carved on its façade. Despite multiple reformations in the 17th and 18th centuries, it still retains the defining features of its nobility, led by the Cadórniga family, the lords of A Mezquita and many other towns of Castile and Leon.
The most important feature of the building is the decoration of its façade, where the semi-circular arch of the façade formed by large voussoirs is enriched with a moulding by way of an alfiz finished in a corbel decorated with balls. This decorated alfiz outline is repeated in the original window preserved on the first floor. On this a quadrangular stone forms the lintel and was probably placed in a period subsequent to the building construction, and which bears a Spanish coat of arms probably from the mid-16th century. The external stone staircase provides access to the first floor of the building, where there is another coat of arms sculpted over a single ashlar framed by a carefully carved ring, it bears arms of the Sarmiento and the Cadórniga.
The external walls are made up of small granite ashlars with rounded edges. The numerous different quarry marks stand out which identify each of the ashlars, enabling them to be counted afterwards and receive the corresponding sum for their creation.
