Puma Punku in Bolivia is one of the world’s most mysterious ancient sites. This remains true for both academic archaeologists and historians as well as rogue historians who investigate the hypothesis of advanced prehistoric civilizations or ancient assistance from extraterrestrials.
Puma Punku covers a large part of the massive ancient city of Tiwanaku and it is located just southeast of Lake Titicaca in the Andes. The city predates Inca presence in that part of South America.
The mystery lies in the precision and complexity of the structures that pervade the ruin. The finely cut doorways and remaining stone blocks bear no chisel marks and many interlock with very fine precision.
According to Jason Yaeger, professor of anthropology at the University of Wisconsin, the city was already abandoned when the Incas conquered the area in 1470. The Incas spared no expense, however, incorporating Puma Punku and the rest of Tiwanaku city into their empire and culture.
Early explorer and engineer Arthur Posnansky, one of the first modern explorers of the site, dated Puma Punku to about 15,000 B.C.; modern archaeologist Neil Steede stands behind Posnansky’s claim.
Posnansky used the astronomical alignments of the site’s main temple to date it. “They built the temple itself as a giant clock,” Steede said in an interview with Forbidden History.
On the first day of spring, the sun rises directly above the center of the temple, through a stone archway. The sunrise moves along the horizon as the days of the year pass. Posnansky expected to find the sun rise above cornerstones on either side of the temple on the summer and winter solstices, but found it rose some distance off.
Looking at where the sunrise would have been 17,000 years ago on the solstices, however, the cornerstones align.
Bolivian archaeologist Dr. Oswald Rivera agrees that the temple was built with astronomical alignments. The buildings are deliberately oriented to the cardinal points.
Other features of the site include a complex irrigation system and smoothly drilled holes and channels in certain stone blocks that seem to defy the stonework of the Incas or known pre-Inca peoples in the region.
