Not the one I'm referring to. Which I just looked up and got the region wrong -- it was in Mesopotamia. It was an actual museum showing ancient artifacts in a building, 2,500 years ago. Some of the things in that museum were an additional 1,500 years old at the time they were on display.
It's a funny story because the modern archeologists who dug it up were very confused by finding objects from different regions and separated by hundreds or thousands of years, all in the same layer.
