Well, it seems like this was an easy one for most of you. The answer is: the Parthenon which is located on the Acropolis of Athens in Greece.
The Elgin Marbles are the collection of Greek sculptures (the frieze, metopes and pediments) from the Parthenon. They were removed from Ottoman-occupied Greece and shipped to Britain by agents of Thomas Bruce, 7th Earl of Elgin. They are now held in the British Museum in London. The large majority of these sculptures were created in the 5th century BC under the direction of sculptor and architect Phidias.
