In an archaeological investigation of modern-day Mexico City, archaeologists could possibly discover:
remnants of temples from Tenochtitlán
Tenochtitlán was the capital of the Aztec Empire, and its ruins are located beneath modern-day Mexico City. The other options, such as the Coricancha and Machu Picchu, are related to different locations in Peru. Colonial Catholic churches could also be found, but they are not as closely tied to the specific archaeological context of Tenochtitlán.
