Workers clean the windows of the new Acropolis Museum, designed by US-based architect Bernard Tschumi, as it braces for the transfer of thousands of precious artifacts, starting Sunday. Three cranes will be used for the delicate operation that is expected to last at least 38 days. A test run is scheduled today. Controversy persists over plans to demolish two listed buildings on Dionysiou Areopagitou St, near the museum’s entrance, which partly block the view to the Parthenon.
