The Shio-Mgvime monastery (Georgian: შიომღვიმე, Shiomghvime, literally meaning "the cave of Shio") is a medieval monastic complex in Georgia, near the town of Mtskheta. It is located in a narrow limestone canyon on the northern bank of the Kura River, some 30 km from Tbilisi, Georgia’s capital.
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 subsequently named Shiomghvime ("the Cave of Shio") after him. The earliest building – the Monastery of St. John the Baptist – a cruciform church, very plain and strict in its design, indeed dates to that time, c. 560s-580s, and the caves curved 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 conic floor and once housed a masterfully ornate stone iconostasis which is now on display at the Art Museum of Georgia in Tbilisi. The monastery was somewhat altered in the 11th and 18th centuries, but has largely retained its original architecture.
The Upper Church (zemo eklesia) named after the Theotokos is a central part of the Shio-Mgvime complex constructed at the verge 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 directly communicates 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 2 km long aqueduct supplying the monastic communities from the nearby village of Skhaltba, and chronicled in 1202 as being constructed by Bishop Anton of Chkondidi, a minister at Queen Thamar’s court.
