On the corner of Calle del Correo and Soportal de Guadalupe is the house known as Mariscal Lanzagorta, named so because it was once home to the rebel of the same name. It is also called by some "casa quemada" or "burned house," because of a fire that happened here. The large window and niche of the facade are new. One of the descendants of Mariscal Lanzagorta built the section of Soportal de Guadalupe belonging to the house.

House number 12 is known as Casa del Mayorazgo. This was the first post office, which was managed by Pedro Sauto, heir to the Sauto fortune. On the right side of the door, you can still see the mail slot.

The Casa del Mayorazgo de Sauto extends to the corner with Calle Josefa Ortiz de Domínguez. The upper levels house Federal Treasury Department offices, and the lower level is a post office.

House number 17 is wrongly called the house of “Pachón.” We say wrongly because the heroic native of the town of San Felipe, J. Encarnación Ortiz, nicknamed "Pachón," never lived here. The mansion belonged to Antonio Agustín Guerrero de Ocio Vázquez y Cuervo, heir to the Guerrero fortune, who married María Josefa Carlota de Allende y Montemayor, niece of General Ignacio Allende y Unzaga in San Miguel el Grande on June 3, 1882. The mansion was built in 1797 by the Count of Jaral de Berrio.

Building number 6 is the former barracks of the regiment Dragones de la Reina, led by Colonel Narciso María Loreto de la Canal.
