According to a historic tradition, the first monastic community at this place was founded by the 6th-century
monk Shio, one of the
Thirteen Assyrian Fathers who came to Georgia as
Christian missionaries. St. Shio is said to have spent his last years as a hermit in a deep cave near Mtskheta, which was subsequently named ("the Cave of Shio") after him. The earliest building, the Monastery of St.
John the Baptist, is a cruciform church, very plain and strict in its design, and indeed dates to that time, . The caves carved by monks are still visible around the monastery and along the road leading to the complex. The church has an octagonal
dome covered with a conical roof and once housed a masterfully ornate stone iconostasis, now on display at the
Art Museum of Georgia in Tbilisi. The monastery was modified in the 11th and 18th centuries, but has largely retained its original architecture. The Upper Church () named after the
Theotokos is a central part of the Shio-Mgvime complex, and was constructed at the turn of the 12th century at the behest of King
David IV of Georgia. Initially a domed church, it was subsequently destroyed by a foreign invasion and restored in 1678 as a
basilica. A refectory was built between the 12th and 17th centuries and is directly connected with the Cave of St. Shio. A 12th-century small
chapel adorned with medieval murals stands separately on a nearby hill. An archaeological expedition revealed, in 1937, a long
aqueduct supplying the monastic communities from the nearby village of Skhaltba, an aqueduct chronicled in 1202 as having been constructed by Bishop Anton of Chkondidi, a minister at
Queen Thamar's court. == History ==
