I'm not in the archeological circle, but was intriged this summer when visiting London, and the museum specifically. It's incredible the huge colection they have, and I was driven by my thoghts on why are this objects in London instead of the places they were found (in a general side). I feel is wrong.

What's the stand point of the archeology professional corpus? should items be remained as close as possible to the place where found? or can be taken to another place/country?

Shouldn't there be any returning programs for those items already moved?

Would like to know... thanks!
