· Many of the secrets of Mexico City are trapped in the wonderful smells of the street vendors and the colors of the markets.
· El Zócalo, or Plaza de la Constitución, is the heart of the city’s historic center: a magical space where seven centuries of history coexist, from the pre-Hispanic to the revolutionary eras. Around the square sit important buildings, such as the National Palace, the Cathedral and the City Hall. In the soil beneath El Zócalo archaeological remains, such as the Stone of the Sun, well known as the Aztec Calendar, have been found.
· Mexico City has the most museums in the world, with more than 160 - almost all of which are free on Sundays!
