They Built the Marvelous City Tenochtitlan on One of the most Difficult Terrains

Tenochtitlan was a little swampy island in Lake Texcoco in the Valley of Mexico when the Aztecs established it. They had to overcome numerous obstacles, including laying a solid foundation for their buildings in the swampy ground, supplying clean water to the city, linking the city to the mainland, safeguarding it from floods, and generating enough food for the city's growing population. Despite these obstacles, the Aztecs built one of the greatest cities of the time on that site.

Tenochtitlan was the largest city in the Pre-Columbian Americas at one time. It had an estimated population of 200,000 to 300,000 people and had an estimated size of 8 to 13.5 km2. It was one of the world's largest cities, with twice the population of London or Rome. When the Spanish arrived in Tenochtitlan, they were so taken aback by the city's streets, causeways, canals, aqueducts, marketplaces, palaces, and temples that they wondered if they were dreaming. With many archives, certainly it is one of the interesting facts about the Aztecs and their empire.

So, they built the Mervelous City Tenochtilan on one of the most difficult terrains. According to the legend, The Aztec god Huitzilopochtli is claimed to have told the Aztecs to look for their city where they saw an eagle perched on a cactus with a serpent in its talons (which is on the current Mexican flag). On the little island where Tenochtitlan was constructed, the Aztecs supposedly had this vision.
