Hi everyone,
As a Greek, I'm quite sensitive in this topic, since Alan pointed out about the Elgin marbles. I would like to add here that the way that someone removes the object from it's birthplace, is also very important. Like in this case of the marbles from Parthenon, they were removed with the worst way, literarly destroying the artifacts in many ways. Not to mention that the weather condition in their "second house" is in many cases not suitable for preserving them in the first place (for example the warm weather without humidity of the meditarrannean area is of no match with the british enviroment). This of course happens with our artifacts (keris).
