Bolnisi Sioni, Basilica in Bolnisi, Georgia.

Bolnisi Sioni is a three-nave basilica in the Kvemo Kartli region, positioned at an elevation of 624 meters. The structure combines classical Georgian building traditions with Persian artistic influences in its stonework.

Built in 478–493 under Bishop David, Bolnisi Sioni is the oldest surviving church in Georgia. Its Georgian inscriptions are among the earliest records of the Georgian alphabet, and it is the first Georgian building to carry its completion date on the exterior. In the 17th century the vaults were rebuilt with supporting arches and a west entrance was cut; restoration work followed in 1936–1939 and 1967–1969.

The church displays decorative carvings with curling vine patterns and interlaced ornaments that recall Persian artistic traditions. You can see these details especially on the southern side and central section of the exterior.

The building is regularly open to visitors and you can examine the early Georgian inscriptions carved into the stone walls. Clear markers help you navigate the site and notice the main architectural features.

The Bolnisi inscriptions on the exterior walls are among the oldest surviving examples of the Georgian alphabet. They also record the church's completion, making it the first Georgian building to carry such a date on its facade.
