The Gialia Monastery is a ruined medieval Georgian Orthodox monastery dedicated to the Virgin Mary. Located in a forest some five kilometers from the coast near the small town of Polis Chrysochous, the ruins were identified, in 1981, by the Georgian scholar Wachtang Djobadze of California State University on the basis of the medieval Georgian accounts. It was not, however, until 2006 that a systematic archaeological research followed after the Georgian and Cypriot governments agreed to jointly investigate the ruins.
It was reported in 2008 that excavation evidence indicated the monastery was commissioned in the late 10th century by Georgian King David III Kuropalates and that renovations were made during the reign of David IV Aghmashenebeli (1089-1125). The monastery is certainly attested in the 12th century, when it was renovated at the behest of Queen Tamar of Georgia (1184-1213). Ancient Georgian sources report that it was in Georgian ownership until the 14th century, and graves and other items uncovered indicate that it was in use between the 14th and 16th centuries. It was reportedly plundered and destroyed in the 16th century, but appears to have been in use as recently as 1935, until final destruction by an earthquake in 1953.
Two main structures have been identified: the earlier Virgin church, and the later St. George's church dated probably to the 11th and 12th centuries respectively. Remains of Georgian paintings and inscriptions from the 13th and 14th century have also survived.
The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
