Located 20km (12 miles) to the northwest of Tbilisi, this town, which has been declared a UNESCO World Heritage Site, predated Tbilisi as the capital of Ibera until the fifth century AD, and remained the center of Georgian Christianity until the 12th century. The 15th-century Svetitskhoveli Cathedral (Pillar of Life), standing at the confluence of the Mtkvari and Aragvi rivers, was the holiest place in old Georgia. According to legend, the church is built on the spot where Christ’s crucifixion robe was dropped to the ground in AD 328, having been brought from Jerusalem by a local Jew, and fragments of the robe are said to be kept inside the cathedral. The existing church has some impressive royal tombs, a fine icon stand and distinctive carved decoration, including bulls’ heads and semi-pagan fertility symbols. Also of interest are the Samtavro Monastery (still functioning although founded in the 11th century, it is famous as the burial place for the first Christian king, Mirian and his wife Nana) and the sixth-century Jvari Cathedral, the design of which became a prototype for Georgian ecclesiastical architecture.
