There is also another kind of movement, think for instance of egyptian
obelisks: they used to stand for hundreds and thousands of years in
egypt, but were then transportated to other places (many of them are
in Rome). It would be interesting to have a relation between the
original place and the place they are now. There is a lot of other
stuff with similar characteristics/history but less prominence (e.g.
columns that have been taken after a war, moved and reintegrated into
newer structures, ...).

Spoils in general, if it is still known where they come from, are
examples for this phenomenon.

In other cases it might be disputable whether it makes sense to map
them in OSM, e.g. a metal sculpture that was molten and a different
sculpture in a different place was made of. An example that comes to
my mind is the victory column in Berlin:
* it was made after the German-French War of 1870/71 and errected in
front of the Reichstag:

* in the nazi times it was raised by one segment and moved from there
to their new East-West-axxis where it stands until now (the other
allies refused the french request to tear it down after 2nd WW):

On a microlevel there are cannons from the wars attached to the column
and there are bronze plates telling the story of the wars from the
contemporary German point of view which were made from conquered
cannons of these wars.
