Conservationists in Turkey have announced a technological breakthrough in the protection of the Lycian rock-cut tombs at Myra. Using a new 'Ionic-Exchange' Nanofilm, researchers have successfully applied a microscopic, breathable protective layer to the soft limestone facades of the 2,500-year-old funerary monuments. This nanotechnology works by chemically bonding to the stone’s surface, preventing the penetration of moisture and atmospheric pollutants while allowing the stone to 'breathe.'
The project, a collaboration between Turkish heritage authorities and European nanotechnologists, aims to halt the accelerating erosion caused by increasingly frequent sandstorms and rising humidity. Initial trials show a 90% reduction in surface flaking without altering the visual appearance or texture of the ancient carvings. This successful application is expected to serve as a model for preserving other threatened rock-cut heritage sites across the Mediterranean and Middle East.
