Its isolated location on top of a steep mountain surrounded by the vastness of nature has made it a symbol for Georgia.
The 18th century Georgian author Vakhushti Batonishvili wrote that in times of danger, precious relics from Mtskheta, including Saint Nino's Cross were brought here for safekeeping.
During the Soviet era, all religious services were prohibited, but the church remained a popular tourist destination.
The northern wall is the most simply decorated one: short-armed cross above and rounded ornamented stones below the narrow window.
Both southern and western portals have rich decorations around the doors: the astragal, ornamented stripe, rosettes and quadrangles.
