World Heritage Sites connected to 'Passage of the Sun':

  • Brú na Bóinne Newgrange has a remarkable Winter Solstice event
  • Chichen-Itza "El Castillo appears to be oriented so that the west plane of the pyramid faces the "Zenith passage". Thus at the spring and fall equinoxes (and for a week before and after) as the sun sets, a play of light and shadow creates the appearance of a snake that gradually undulates down the stairway of the pyramid. This diamond-backed snake is composed of seven or so triangular shadows, cast by the stepped terraces of the pyramid"

These dates are allegedly the king's birthday and coronation day respectively, but there is no evidence to support this"
