Iron Age Scots Built a 2,000-Year-Old Hot Tub — And It Still Works #Shorts - Video

Scotland's oldest sauna predates Rome by 500 years.

Archaeologists just uncovered a stone-lined basin in the Scottish Highlands. It's 2,000 years old. The structure sits near a burn, fed by a channel carved into bedrock. Charred stones fill a hearth pit nearby. The Iron Age builders heated rocks, dropped them into the water, and created steam. But the basin still holds water today. The ancient Picts engineered a waterproof seal using clay and stone that survived two millennia of freeze-thaw cycles. Modern concrete cracks in 50 years. Their ritualized bathing culture vanished when Rome arrived, but the engineering didn't.
