The "Casa del Deán" is one of the most iconic buildings in the city of Puebla. It is considered the oldest standing civil structure in the noble city of "Puebla de los Ángeles" and served as an architectural precedent for the construction of the city's cathedral. Built between 1564 and 1580, the house was commissioned by Tomás de la Plaza y Goes, the third dean of the cathedral chapter.

Constructed in 1899 as a hospital, this national heritage building is now used by various institutions and includes the exhibition galleries of the National Institute of Anthropology and History (INAH) for the state of Durango, with a large collection of objects on the pre-Hispanic Chachihuite culture and a space for temporary exhibitions.
