What is now the downtown of Mexico City correlates with the ancient island in Lake Texcoco and founded in this place in 1325 the Aztecs capital of Tenochtitlan. Modern capital city of Mexico stands on the lakebed of drained wetlands and on the ruins of a completely demolished pre-Columbian city.
After the destruction of Tenochtitlan, the location of major parts of the Aztec city was forgotten. So was in the case of the Templo Mayor or Great Temple, until the second half of the 20th century. At that time, several buildings were demolished, and archeologists uncovered not only the remains the temple, but also the House of Eagles Warriors, a place where elites held their ceremonies.
