Was there a massive pyramid in the U.S. that’s bigger at its base than the Great Pyramid of Giza— yet almost no one talks about it? It wasn’t built by the Egyptians. Nor any civilization you’ve heard of in school. So who really built Monks Mound?

The Great Pyramid, built around 2560 BCE, was the tallest structure in the world for nearly 4,000 years. Monks Mound? Built between 900-1200 CE by a mysterious culture known as the Mississippians among other names.

Here’s where it gets wild:
•The Great Pyramid’s base covers 13.1 acres.
•Monks Mound? 14 acres—larger.

Yet Monks Mound was built without stone. Just soil, clay, and sand—22 million cubic feet of it. All moved by hand.

How? And why?

Both structures show insane mathematical precision.
•The Great Pyramid aligns perfectly with true north.
•Monks Mound was carefully aligned with the sun, marking solstices and equinoxes like a prehistoric clock.

Were these civilizations tapping into the same lost knowledge?

Experts say Monks Mound was built by Cahokia’s people. But here’s the thing:
•The Mississippians had no written language.
•No records explain how or why they built this.
•By the time Europeans arrived, Cahokia was completely abandoned.

Just… gone.

Alternative history/ancient archaeology in this sub is a bold move.

Bring up actual conspiratorial/cover-up theories from our ancient past and people usually lose their shit.
