The Vatican has returned three fragments of the Parthenon sculptures to Greece in a move that has been described as a "gesture of friendship".
Ednews reports citing BBC that the decision to return the 2,500-year-old marbles was announced by Pope Francis last year.
One is a chunk of a horses head, the other a bearded man and the third a head of a boy.
Greece hopes the move will spur other overseas institutions that hold Parthenon sculptures to return them.
About 50% of the Parthenon's original sculptures have survived and almost half of them are in the British Museum.
"The ceremony today... similar to the gesture by the government of Sicily and the Republic of Italy a few months ago, shows the road that we could follow, that everyone could follow, in order for the unity of the Parthenon to be restored," Greece's culture minister Linda Mendoni said on Friday.
As the marbles were returned, dignitaries exchanged hand shakes and smiled in front of the cameras, including the leader of the Greek Orthodox Church, Archbishop Ieronymous.
"My personal heartfelt wish is that this initiative is mimicked by others. Pope Francis showed that this is possible and significant," he said.
