Texcoco is a city and municipality located in the State of Mexico, 25 km northeast of Mexico City. In the pre-Hispanic era, this was a major Aztec city on the shores of Lake Texcoco. After the Conquest, the city was initially the second most important after Mexico City, but its importance faded over time, becoming more rural in character. Over the colonial and post-independence periods, most of Lake Texcoco was drained and the city is no longer on the shore and much of the municipality is on lakebed. Numerous Aztec archeological finds have been discovered here, including the 125,000 kilo stone statue of Tlaloc, which now resides at the Museum of Anthropology in Mexico City.
