The Acropolis Musem is one of the most important museums in the world. It temporarily houses masterpieces of the ancient Greek civilization, dedicated to the most important of the Athenian sanctuaries, the "temenos" of Athena Parthenos. Preparations for the erection of the New Acropolis Museum have already begun.
Many of the unique works of art that ornamented the Acropolis have been stolen and transferred abroad. The worst plundering of the monuments took place in the beginning of the 19th century by Lord Elgin.

The Acropolis museum was designed by the architect Panages Kalkos and constructed between 1865 and 1874. In the 1950's it was extended towards the east and the exhibition was rearranged by the archaeologist I. Meliades. The museum contains only the stone sculptures from the monuments of the Acropolis and from the excavations on the site. Since the beginning of the excavations, the vases and the bronzes have been kept in the National Archaeological Museum of Athens, while the inscriptions are housed in the Epigraphical Museum.

The collections of the Acropolis museum includes:

• Sculptural offerings of the Archaic period
• Pediments of temples dated to the Archaic period
• Archaic Horsemen
• Sculptures of the "Severe" style
• Pediments and metopes from the Parthenon
• The Parthenon frieze
• The Erechtheion frieze
• Parapets of the Athena Nike temple
• Frieze of the Athena Nike temple
• The Caryatids
• Clay figurines and vases from the sanctuary of the Nymphs.
