The Holy Monastery of Saint Catherine is the world's oldest continuously operating Christian monastery. Commissioned by the Byzantine emperor Justinian in the sixth century, it contains works of art and historic documents of tremendous beauty and importance including icons, wall paintings, and mosaics. One of the most famous of these is the Transfiguration mosaic, a jewel of early Byzantine art, located in the apse over the high altar in the monastery's basilica.

Over the centuries, the Transfiguration has suffered extensive damage from earthquakes and intense visitation by pilgrims from all corners of the world. The Center for Archaeological Conservation (CCA), in Rome, has recently completed a five-year project to conserve this priceless mosaic.

On April 14, 2011 conservator and archaeologist Roberto Nardi, founder of CCA, recounted the steps taken to conserve and safeguard this iconic work or art.
