The Houses of the Mayorazgo de Guerrero are buildings in Mexico City located on 16 and 18 Moneda Street, across from the Museum of Cultures, straddling Correo Mayor Street. Across the street from Museum of Cultures near Correo Mayor. The two buildings are nearly twins, both with tezontle stone facades and white stone accents. The houses were founded by the family of Juan Guerrero de Luna in the 16th century, and stayed in the family all through the colonial period as a permanent grant of the Spanish Crown. The current appearance of the buildings is due to rebuilding which was realized in the late 18th century.
