The Olympic Tower is a 52-storey skyscraper located on 5th Avenue, and 51st street in New York. In 1998 a multi-million USD renovation program started to improve the building’s main lobby and major mechanical and electrical systems. The project was a complete refurbishment of the entrance lobby, which has an area of 1000 m2, a height of 10m and includes a waterfall and a skylight. This “atrium” is decorated with 19th century plaster casts of the Parthenon freeze, of remarkable quality and historical value, the originals of which are in the British Museum.
