The beautiful gray quarry facade is the surviving part of the Dean's house, named after its former owner, a Dean or Treasurer of the Puebla Cathedral.

It dates back to 1580, according to the sgraffito on its Renaissance-style entrance. The architect and builder was Francisco de Becerra, who also designed part of the Puebla Cathedral.

The most notable feature of the house is the mural paintings inside. This type of decoration was common in religious buildings but not as much in civil constructions. Moreover, these artistic representations are some of the few examples still visible in all of America.

There are two rooms where you can appreciate this pictorial art. The first showcases the mural "The Procession of the Sibyls," depicting the prophetesses who announced the coming, passion, and death of Jesus Christ. The second room features a mural known as "The Triumphs," reproducing copies of engravings that illustrated the verses of the Italian poet Francesco Petrarca.

It is believed that the design of these murals was influenced by Flemish tapestries, which were widely used in European decoration.
