The Acropolis Museum is an Archaeological Museum focused on the findings of the archaeological site of the Acropolis of Athens. The museum was built to house every artifact found on the rock and on its feet, from the Greek Bronze Age to Roman and Byzantine Greece. It also lies on the archaeological site of Makrygianni and the ruins of a part of Roman and early Byzantine Athens.The museum was founded in 2003, while the Organization of the Museum was established in 2008. It opened to the public on June 21, 2009. Nearly 4,000 objects are exhibited over an area of 14,000 square metres.The Organization for the Construction of the new museum is chaired by Aristotle University of Thessaloniki Professor Emeritus of Archaeology, Dimitrios Pandermalis.The first museum was on the Acropolis, (see Old Acropolis Museum); it was completed in 1874 and underwent a moderate expansion in the 1950s. However, successive excavations on the Acropolis uncovered many new artifacts which significantly exceeded its original capacity.
