The Kalasasaya ( Aymara: kala = rock, saya or sayasta = standing), who is "place of standing stones " of the central square of the ancient ruins of Tiahuanaco in Bolivia.

The Kalasasaya (also: Kalasaya ) has a raised central square of rectangular shape, having a length of 129 meters and a width of 118 meters, is surrounded by upright monoliths and is oriented to the four cardinal directions. East of the square is a semi- subterranean temple, from which a staircase leads up to a gate. On the day of the equinox, the sun rises in the center of this door. Scientists therefore see the Kalasasaya as a solar observatory from the pre- Inca times.

The exact origin of the period Kalasasaya is the subject of scientific speculation. During the investigations of Arthur Posnansky suggest an age of 12,000 years, radio -carbon measurements can be rather suggest an age of 2000 years.
