The stunning ruins of Chichén Itzá are evidence of a sensational ancient city that was the centre of the Mayan Empire in Central America. The largest and the most impressive of Mayan ruins, Chichén Itzá today has become the most prominent tourist attraction in Mexico. And the step pyramid, the one that is the most recognisable monument in the area, is called Kukulkan's Pyramid or El Castillo. These ruins are a great reflection of the advanced stage of science and astronomy that the Mayan culture was capable of. The step-pyramid itself has 365 steps, one each for every day of the calendar!
This is an amazing pre-Colombian archaeological place that I had somehow missed on my journey, until I was pointed to it on my way someplace else. Tlatelolco was built by the Aztecs when one group of them built Templo Mayor (now in the center of Mexico City next to Zocalo main square) and the second group settled down and built Tlatelolco where it stands here. The main temple is said to be at least 700 years old which proves its construction by both Aztecs and Tlatelolca tribes. Tlatelolco stands in the middle of what it is called nowadays as Plaza de tres culturas – Square of the Three Cultures where three cultures of Mexican history blend. The three cultures being Pre-Colombian, Spanish and modern mestizo (represented by the former office buildings of foreign ministry in the southern part of the square)
