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. After Independence, the two houses gradually fell out of family hands, with the main house serving various public functions and the smaller house becoming apartments and shops.
