Isn't that just like our normal museums now ?

Yes but much further in the future when someone else digs them up.

No, the artifacts stayed where they were found. Different concept.

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.

You must have been cheering when they blew up the Buddhas of Bamiyan because at least white people didn't have them.

We had a party and everything. If you meet the Buddha on the road ...

Also dinosaur bones.

  As Mayor shows, the Greeks and Romans were well aware that a different breed 
  of creatures once inhabited their lands. They frequently encountered the 
  fossilized bones of these primeval beings, and they developed sophisticated 
  concepts to explain the fossil evidence, concepts that were expressed in 
  mythological stories. . . .

  Like their modern counterparts, the ancient fossil hunters collected and 
  measured impressive petrified remains and displayed them in temples and 
  museums; they attempted to reconstruct the appearance of these prehistoric 
  creatures and to explain their extinction. . . .
