Reached through a forest, the domed church of Moni Thari was hidden from view in order to escape the attention of marauding pirates. According to legend, it was built in the 9th century by a mortally ill Byzantine princess, who miraculously recovered when it was completed.
The 12th-century north and south walls remain, and there are vestiges of the 9th-century building in the grounds. The nave, apse and dome are covered with frescoes. Some walls have four layers of paintings, the earliest dating as far back as 1100, while there are three layers in the apse dating from the 12th-16th centuries. These are more distinct, and depict a group of prophets and a horse’s head. The monastery has been extended and has basic accommodation for visitors.
References: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.
