00:00Deep in the high mountains of Bolivia, near Lake Titicaca, lies a fascinating place called
00:06Pumapangu.
00:07It's part of an old city named Tiwanaku, built around 536 AD by the Tiwanaku people.
00:15This civilization was very important in South America long before the Inca, lasting from
00:21about 300 to 1000 AD.
00:24But we knew surprisingly little about them because they did not write anything down.
00:29We don't even know exactly where they came from or why they built Pumapangu.
00:36What makes Pumapangu special is how incredibly well it's built.
00:41The stonework is unlike anything else from the ancient times.
00:45Huge blocks of sandstone and andesite rock, some heavier than 20 elephants, were carved
00:51with amazing precision.
00:53These stones fit together perfectly, like puzzle pieces.
00:57Even today, after hundreds of years, you can't slide a razor blade between them.
01:03Scientists have ideas.
01:04Maybe they have special tools or perhaps they used a kind of ancient concrete.
01:09But even with modern technology, we haven't solved these puzzles.
01:13That's why Pumapangu is so captivating.
01:16It's not just the amazing stonework, it's all the unanswered questions that keep drawing
01:22people back, hoping to finally unlock the secrets hidden in its stone.
01:27Pumapangu means the door of the Puma, in the Aymara language, is one of the most mysterious
01:33and fascinating ancient archaeological sites in the world.
01:37This site is situated at an altitude of approximately 12,800 feet above sea level, which makes the
01:45construction of such a sophisticated structure even more surprising considering the lack of
01:51oxygen and harsh climate at that height.
01:54The site contains massive stone blocks, some weighing more than 100 tons, which were carved
02:00with astonishing accuracy.
02:03These blocks are made of extremely hard materials such as granite and diorite.
02:08These are the types of rocks that are even harder than iron.
02:12What's more impressive is that the stone blocks are cut with perfectly straight lines, smooth
02:18surfaces and exact right angles.
02:21Many of these stone shapes like puzzle pieces designed to interlock perfectly without the
02:27use of mortar or cement.
02:29Even today with modern tools, it would be a difficult task to recreate such precise cuts.
02:35This has led many to question how an ancient civilization, supposedly without iron tools or advanced
02:42technology, could accomplish such a feat over a thousand years ago.
02:47The mystery of how these massive stones were transported to the site only adds to the puzzle.
02:53Some of the stones came from quarries located over 50 miles away.
02:57The Tiwanaku people did not have wheel carts or pack animals like horses or oxen, which raises
03:04even more questions.
03:06How did they move these gigantic stones across mountains and rugged terrain?
03:11Some scientists believe they use simple tools, ropes and lots of manpower.
03:16But others argue that these explanations do not fully account for the level of precision
03:22and the sheer size of the materials.
03:24This is why Puma Bhankyo has become a popular subject of alternative theories, including suggestions
03:31that ancient astronauts or extraterritorial beings may have been involved in its construction.
03:38Although these ideas are widely popular in documentaries and books.
03:43However, mainstream archaeologists do not support the alien theory as there is no scientific evidence
03:49to prove it.
03:50Despite its ruined conditions today, archaeologists believe that Puma Bhankyo was once a grand ceremonial
03:57platform or temple complex.
03:59It likely served as a sacred place for religious and spiritual gathering.
04:04The layout of the site suggests that it may have been aligned with the stars or solar events,
04:10which indicates the builders have a deep understanding of astronomy and mathematics.
04:16Some of the most famous features at the site include the H blocks, which are precisely shaped
04:21stones that look like the latter H and fit together with other stones like parts of a machine.
04:28These structures along the carved motifs and symmetrical designs show that the builders were
04:34not only skilled engineers but also highly artistic and intelligent.
04:39Puma Bhankyo remains one of the most intriguing ancient sites in the world, not just because
04:44of its age and location, but because of the advanced techniques used to cut shape and place enormous
04:50stones with incredible precision.
04:52It challenges our understanding of what ancient people were capable of and opens the door to
04:58many questions about lost knowledge, ancient technology and human history.
05:04While many mysteries still surround Puma Bhankyo, it stands as a powerful reminder that ancient civilization
05:10may have been seen for more advanced than we often imagine.
05:15Whether built through unknown ancient techniques or by clever engineering, using tools now lost
05:21to time, Puma Bhankyo continues to amaze and inspire researchers, explorers, and curious minds
05:27around the globe.
05:33So, let's see.
05:44Let's see.
