The construction of the Aztecs’ metropolis on the island of Tenochtitlan is considered to be one of the most significant technological accomplishments of their civilization.
By constructing man-made islands known as chinampas, the Aztecs were able to increase the size of the city’s landmass.
They began by constructing a bed of dirt for the chinampa by piling stones and mud on top of a mat made of reeds.
This step was the first step in the construction of the chinampa.
