Using radar equipment, archaeologists have located the tomb of the Aztec ruler Ahuizotl 15 feet below a ceremonial center in the heart of Mexico City. The tomb is large, consisting of several chambers.
Ahuizotl was the uncle of Moctezuma, who led the Aztec emperor at the time of the conquest by Hernán Cortés. He was cremated in 1502 according to a large monolith that was recently discovered, prompting the search for his tomb. From an article about plans to excavate the tomb:
Leonardo López Luján, the lead archaeologist, told Associated Press that his team hoped to be inside the chambers by October, staring at the ashes of Ahuizotl, as well as offerings befitting his status as the last Aztec ruler to die in power.
The team was moving slowly because the entrance is flooded and filled with rocks, forcing the need for pumps to keep the water level down as archaeologists excavate while hanging from slings, he said. He said the conditions may have helped preserve the tomb’s contents.
