At Puma Punku in Peru, located at an altitude of more than 3,9 km, there are giant blocks of stones weighing more than 100 tons. These blocks have just fallen into place, and today they are scattered like baby cubes.

There are still remnants of huge walls in the fortress of Sacsayhuaman near Cuzco. When this place was conquered by the Spaniards in Peru, it was said to be the work of the devil, because neither the blade nor the razor blade is in the gaps between the stones. It looks as if the stones were connected in a molten state using a technology we do not even have today.

In Puma Punk, huge stones were cut with absolutely accurate (right) angles and exact patterns. Individual stones look like prefabricated bricks or LEGO blocks.
