The Lincoln Center for the Performing Arts in New York City is world renowned for its architectural prominence and beautiful natural travertine facades. The original campus was completed in the 1960’s using Este Light Travertine 6cm quarried in central Italy. Over time weathering has caused some areas to require extensive maintenance and replacement. Now in 2020 the trustees of Lincoln Center have sought a more advanced solution for replacement while maintaining the original aesthetic and feel of the full stone thickness. Gammastone natural air system is being utilized with new stone from the very same stone quarry as the original pieces from 60 years ago.
