In many towns throughout Mexico, houses still retain blank exteriors facing the street, some with an occasional window. However, beyond these canyon-forming walls, one is exposed to interiors alive with rainbows of color. The front of the house may be one story, but once inside the entrance, a visitor might be exposed to two or more stories, probably with a rooftop terrace and a fantastic view of a downtown skyline. The architecture of the houses reflects eras when Mexico was at peaks in its history and when some buildings were extravagant homes built by famous families.
