Stands at the foot of the castle hill, facing the Plaza del Mercado, and preserves its monumental Renaissance façade as a powerful evocation of the noble past of Berlanga de Duero. Built in the 16th century as the main residence of the lords and later marquesses of Berlanga, it originally formed a large complex with two corner towers, a central Doric-columned courtyard and a broad entrance atrium opening onto the square. From this terrace, twin stairways descended to the plaza while a ramp allowed carriages to reach the principal floor from behind, underlining the palace’s ceremonial and residential function. Inside were a chapel-oratory dedicated to Saint John the Baptist, spacious living quarters and extensive terraced gardens adorned with statues, fountains and baths, irrigated by a waterwheel that lifted water over 120 feet. Severely damaged by fire during the Peninsular War, the palace lost its interiors but retained the long ashlar façade with three storeys and an upper gallery, as well as the great Tovar family coat of arms bearing the Latin motto “Sapientia aedificabis sibi domus et prudentia roborabitur”. Declared a historic-artistic monument in 1980, it is now protected as a cultural asset.
It is located in the old slaughterhouse and features pieces belonging to different churches in the town, as well as a series of explanatory panels, models and an audiovisual presentation to show the splendor lost in the Hermitage of San Baudelio due to the plundering of the paintings through a virtual reconstruction of what the hermitage would have looked like in its origins.
