I saw a long piece on TLC or such about a guy who went to Ethiopia and had lots of footage of the chapel housing the ARK. It's on an island somewhere in Ethiopia. The photo above is probably a file photo and not real. The folks in Ethiopis think the ARK is there. Only one guy sees it and it is never on public display. He made a very strong case that if not the ARk there is something very holy there and it has been there for a very very long time.
My own thought is that the Ark was removed from Jerusalem. There are bias relief sculptures in Rome indicating the Ark was brought to Rome by hadrian with orther treasures but no knoelwdge of what happened to it in Rome.
No, the Ark is never pictured in Rome.
Could not have been, of course, for it was never even in the Second Temple, built c517 BC...
It had already been put down in the tunnel by Jeremiah and Baruch c610 BC.
