ASTRONOMY, GEOMETRIE AND ARCHITECTURE IN CHICHENITZA

New observations corroborate that The Castle, the principal pyramid of the ancient city of Chichan Itza, in Yucatan, was point towards and is useful as an astronomical sign, since the wise Mayas of the Pos-classic adjusted the year, and to be the centre of a cosmograma, which has an alignment in his four cardinal points, this alignment with the springs: Sagrado, Holtun, Xtoloc y Kanjuyum. In 2012, the archeologist Ismael Arturo Montero Garcia showed in the magazine National Geographic corresponding to the month of August, year 2013 with a base in direction values-that the zenith way for this pre-Hispanic structure arrives on May 4th and on June 19th, appearing at daybreak in the axle of its north corner towards Templo de las Mesas. The research organizes the geometry, the astronomy, and the architecture in an extraordinary way thanks to the azimuth of the sun when this one wakes up of its zenithal way's day for this geographic latitude and to the peculiar geomorphology of its environment.
