Centuries-old frescoes that decorate the walls of the world-renowned Sumela Monastery in Türkiye’s Black Sea province of Trabzon are being meticulously restored to their original splendor, according to Anadolu Agency.

Also known as Mother Mary or Virgin Mary, the fourth-century monastery overlooks lush Altindere Valley from its 300-meter (984-feet) perch on the side of Mount Karadag, where it is carved into the rock.

Sumela Monastery, listed as a tentative UNESCO world heritage site, was reopened for religious practice on Aug. 15, 2010, after a hiatus of 88 years.

Fresco restoration work began this May, led by Türkiye's General Directorate of Cultural Heritage and Museums, which operates under the country's Culture and Tourism Ministry. The project focuses on repairing damage caused during past visits using undertone and acqua sporca techniques.

The Trabzon Restoration and Conservation Regional Laboratory Directorate has been leading the restoration, bringing scenes like "The Last Supper" back to life.
