El mercado de Tlatelolco was the largest commercial center in Mesoamerica.
There, locals and people from other regions of the Mexica territory exchanged a wide range of products such as fresh fruits and vegetables (corn, squash, avocados, cacao); animals (hares, quails, deer, fishes); clothing (shawls, sandals); construction materials (wood, lime); minerals (jade, silver, gold), and even slaves.
The market also served as a place of social gatherings where people exchanged news and formed alliances, consulted doctors, got haircuts, and ate local food and drinks.
