Gergeti Trinity Church is a popular name for Holy Trinity Church near the village of Gergeti, up from Stepantsminda (Kazbegi) settlement. The church is situated on the right bank of the river Chkheri (the left tributary of the river Terek), at an elevation of 2170 meters, under Mount Mkinvartsveri (often called Kazbek).

The Gergeti Trinity Church was built in the 14th century, and is the only cross-cupola church in Khevi province. The separate belltower dates from the same period as the church itself. 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 church is now an active establishment of the Georgian Orthodox and Apostolic Church.

The church is a popular waypoint for trekkers in the area, and can be reached by a steep 3 hour climb up the mountain, or around 30 minutes by jeep up a rough mountain trail.
