At the beginning of the 19th century, the Mansion was owned by Fray Valarezo, who had it built in between of two Franciscan convents; this one, concealed underground passageways with stone walls and lintels reused from the colonial era, these secret passageways connected the convents below the streets of the city. It is said that this was a place of clandestine meetings of the highest authorities of the church, where important decisions of the local government were made. Also a part of the caves were destined as warehouses of the wealth of the potentate Fray; one of the most precious was its huge cellar of Spanish wines that rested in large oak barrels; part of the cellar was rescued and can now be seen integrated into the bar.
