This building can be seen from the atrium of the Cathedral, and its facade features tile panels representing the bishopric, symbolized by fleurs-de-lis.

During the colonial era, it was the only building in Puebla referred to as a "palace" because it served as the private residence of the bishops since the early 17th century. In 1792, it underwent a significant remodeling that likely resembles its current structure the most.

As a result of the Reform Laws, the building ceased to function as the residence of the bishopric. Between 1861 and 1863, it served as the government palace; in 1914, it was used as a school, and later it was designated as the offices of the Traffic Department.

Currently, it houses the Post Office and Telegraph offices.
