No, Stonehenge Wasn't Built by Druids

Scientific Miscellanea

The Myth:

Stonehenge, the mysterious giant monument in England that looks like a drunken domino game played by God, is a work of the druids -- the priestly caste of an ancient Celtic tribe -- for use in their mysterious ceremonies. This Stonehenge/druid connection pops up everywhere, from the Spinal Tap movie to real-life seasonal druidic ceremonies at Stonehenge, which have been going on since the early 20th century and offer a slightly more socially acceptable way to dress up in white robes and call yourself a wizard.

They're also not afraid to cut any Harry Potter fans who encroach on their turf.

But Actually ...
The fact is, no one knows much about the people who built Stonehenge. The builders didn't leave any written documents or little self-portraits carved into the rocks or anything. We do know one thing, though: It wasn't the druids. Carbon dating puts the finished monument centuries before the Celtic tribe with druid priests even arrived in Britain, and since it took over 1,000 years to build, we're pretty sure that means they weren't around during the initial building consultations.
This isn't exactly surprising, though, because everything we know about druids has them worshiping in oak groves, not in open plains more suitable for picnicking.

Real druids weren't much into the whole "dancing naked under rocks" thing. They hadn't invented Ecstasy.

So how did the monument become so connected with druidism? We can thank 18th century archaeologist William Stukeley, who popularized the theory. Stukeley was a member of a historical re-enactment club in which he played a druid called Chyndonax, and in his spare time was fond of re-enacting druidic ceremonies with his wife (as weird as you think it is, trust us, it's weirder).
So, given that this druid-obsessed dude was basically the 18th century version of the Ancient Aliens Guy, it wasn't surprising that when it came to Stonehenge, his opinion was "Screw it, probably druids." He was the kind of guy who probably thought druids were behind everything.
