We did an overnight visit to Tbilisi, Georgia from Yerevan.. Interesting city, Castle on the hill. Interesting church complexes and a cave city, Vardzia, with over 600 caves that held soldiers and their families at some point in history and also Monasteries and men of God. Giorgi 3 started the cave city and it was finished by Queen Tamar in 1100’s AD. An earthquake in 1283 destroyed the outer walls and so the caves became visible. Did you know that the Georgian flag is the cross of Jesus and then 4 smaller crosses for Mathew, Mark, Luke and John..
