query: What is type of stone is used in the Parthenon?
passage: Elgin Marbles
The Parthenon Marbles (Greek: Γλυπτά του Παρθενώνα), also known as the Elgin Marbles (/ˈɛlɡɪn/), 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.[1][2]
passage: Metopes of the Parthenon
Those that remained in situ throughout the nineteenth and twentieth centuries suffered the onslaught of weather and especially pollution. The metopes were removed from the building in 1988-1989 and deposited at the Acropolis Museum of Athens, along with southern XII. They have been replaced by cement mouldings on the Parthenon. South I, XXIV, XXV and XXVII to north XXXII and the fourteen metopes of the west facade are still in place, sometimes in very bad condition (West VI and VII have lost all their decor), sometimes intact (South I and North XXXII). Many fragments are in various European museums: Rome, Munich, Copenhagen (National Museum of Denmark), Wurzburg (Martin von Wagner Museum), Paris, etc. Other pieces that had been used to strengthen the southern fortification of the Acropolis in the eighteenth century have been removed since the 1980s and 1990s. These could be just as well fragments of southern metopes as north ones.
