Mexico-Tenochtitlan Causeway

The Mexico-Tenochtitlan Causeway was a remarkable roadway system connecting the Aztec capital, Tenochtitlan (located on an island in Lake Texcoco), to the mainland. Built with stones and earth, it consisted of two parallel roads separated by water, allowing for easy access and transportation of people, goods, and military forces. The causeway was crucial for trade, communication, and defense, and featured bridges that could be raised to protect against invaders. It exemplifies advanced engineering and urban planning, facilitating Tenochtitlan’s rise as a powerful, thriving city before Spanish conquest.
