The Elgin Marbles, also known as the Parthenon Marbles, are a collection of Classical Greek marble sculptures made under the supervision of the architect and sculptor Phidias and his assistants. They were originally part of the temple of the Parthenon and other buildings on the Acropolis of Athens. The collection is now on display in the British Museum, in the purpose-built Duveen Gallery.

The marbles were taken from Greece to Malta, then a British protectorate, where they remained for a number of years until they were transported to Britain. The excavation and removal was completed in 1812 at a personal cost to Elgin of £74,240 (equivalent to £4,700,000 in 2019 pounds).

Elgin intended to use the marbles to decorate Broomhall House, his private home near Dunfermline in Scotland, but a costly divorce suit forced him to sell them to settle his debts. Elgin sold the Parthenon Marbles to the British government for £35,000, less than half of what it cost him to procure them, declining higher offers from other potential buyers, including Napoleon.
