Pumapunku

The Pumapunku is a man-made platform built on an east–west axis like the Akapana. It is a rectangular, terraced earthen mound faced with megalithic blocks. It is 167.36 m wide along its north–south axis and 116.7 m broad along its east–west axis, and is 5 m tall. Identical 20-meter-wide projections extend 27.6 meters north and south from the northeast and southeast corners of the Pumapunku. Walled and unwalled courts and an esplanade are associated with this structure.
Most of the structure still lies under the ground with very few parts excavated yet. The blocks of stones are carved from a very hard volcanic stone but still have very precise angles and sides. There are even niches cut as rectangles with perfect 90 degrees angles.Læs mere
