Stonehenge has produced wild origin stories

Stonehenge is one of the world's most studied prehistoric sites and was built around the same time as the Great Pyramid of Egypt.

New scientific tools, such as radiocarbon dating and DNA analysis, have transformed what we know about who built Stonehenge.

Techniques such as radiocarbon dating, DNA analysis, and isotopic testing have revised scholars' understanding of Stonehenge. This article presents evidence suggesting that societies were more cooperative and less violent than earlier theories had suggested.

Researchers once thought Stonehenge functioned as a precise astronomical computer

In the 1960s, scientists used early computers to analyze the stone layout at Stonehenge, arguing it could predict eclipses and other celestial events. This BBC Sky at Night Magazine piece explains how the theory arose—and why scholars now doubt it.

Stonehenge was part of a much larger prehistoric landscape

Long before Stonehenge was built, the Salisbury Plain was already dotted with ceremonial sites, burial mounds, and large-scale earthworks. These landscape maps reveal a densely inhabited region shaped by sophisticated prehistoric communities with ambitious public projects.

Stonehenge was part of a continent-wide "henge" boom

Aliens have invaded ancient history

Avid fans of archaeology can sometimes fall prey to unsubstantiated claims like "aliens built the pyramids," provocative, dubious theories which fall under the category of pseudo-archaeology. Many of these claims are premised on hidden biases toward non-Western cultural heritages. This professor explores the hidden contours of pseudo-archaeology in this 12-minute TED talk.

Machu Picchu, 101

Machu Picchu was built right on top of two intersecting fault lines, which makes it even more baffling how its temples and terraces have survived for more than 500 years—especially since no mortar was used to hold the precisely cut stones together. As this three-minute NatGeo video explains, this ingenious construction method allows the stones to bounce in place when earthquakes hit, shaking and rattling but rarely collapsing.
