There's a replica of the inner circle of Stonehenge in Washington State along the Columbia River. It's known locally as "Concretehenge" because of the material used to create it. It's a memorial to WWI dead.

They didn't get it right when they built it, so it doesn't work to predict eclipses the way the real one does.

Just make sure you know the difference between feet and inches.

"I do not, for one, think that the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf. All right? That tended to understate the hugeness of the object."
