The oldest wooden wheel in Slovenia is 5100 years old

To find very old things made out of wood is difficult. Wood rots, so it’s pretty much a miracle to find anything older than 5,000 years. But that’s what happened in Ljubljana a few years ago. Archaeologists uncovered a wooden wheel that is from 5100 to 5300 years old. That’s at least a century older than wooden wheels dug up in Austria and southern Germany. More than 5 millennia ago, someone in Slovenia made a wheel that was really, really, really built to last.
