" El Caracol " a possible observatory temple at Chichen Itza. The Temple of the Warriors bears iconography depicting feathered serpents associated with Quetzalcoatl or Kukulcan.

This means that the building's alignment towards the place on the horizon where Venus first appears in the evening sky ( when it coincides with the rainy season ) may be meaningful.

Aveni claims that another building associated with the planet Venus in the form of Kukulcan, and the rainy season at Chichen Itza is the Caracol.

This is a building with circular tower and doors facing the cardinal directions.

The base faces the most northerly setting of Venus.

Additionally the pillars of a stylobate on the building's upper platform were painted black and red.

These are colours associated with Venus as an evening and morning star.

However the windows in the tower seem to have been little more than slots, making them poor at letting light in, but providing a suitable place to view out.
