After picking up our travelers at the zócalo, we will make a stop at the square of the three cultures. A magnificent place that architecturally summarizes the identity of Mexico City. We will walk through the ancient ruins of what was, from the 16th century, the most important commercial zone in Mesoamerica until the war for the conquest between the Aztecs and the alliance of Tlaxcaltecas with the Spanish. We will visit the Church of Santiago where the first indigenous person was baptized after the appearance of the Virgin of Guadalupe, San Diego. Likewise, we will know the multifamily buildings work of the architect Mario Pani. They represent the first stage of modernization of Mexico City in the 50s involved in important socio-political movements such as the 68 movement for the arrival of the Olympic games in Mexico City.
