A series of six lectures entitled "The Acropolis Restoration Project and the Laser Application" will be presented at the universities of Columbia, Yale, Pennsylvania, Boston, Delaware and Stony Brook from March 24 to April 4.

The Greek ground-breaking technique of using lasers to clean the surface of antique marbles will be presented by the Institute of Electronic Structure and Laser at the Foundation for Research and Technology (IESL-FORTH) and the Acropolis Monuments Restoration Service (YSMA) and funded by the Onassis Foundation's University Seminars Programme.

The research team IESL - FORTH in Heraklion, Crete, has designed and built an innovative laser system that simultaneously uses two laser beams, allowing the maintainer to remove accurately deposits pollutants from the surface of the sculpture, ensuring that the original substrate does not discolor or suffer some other damage, while revealing the unique surface.
