Ayia Zoni church is in the south east corner of Famagusta, close to St Nikolas' church, and is one of three remaining Byzantine churches in the area. Ayia Zoni is dedicated to the sacred belt of the Virgin Mary. According to tradition, the Holy Belt was made by the Virgin Mary herself out of camel hair. It was approximately 90cm long, with little strings at the end to tie it up. Three days after she died, during her ascension, she gave this belt to the Apostle Thomas. Thomas and the other Apostles opened her grave, but didn't find her body. Thus the belt is seen as proof of her ascension into heaven.
At some point, this church must have had a piece of this cloth, a sacred relic of the clothing of Mary. Ayia Zoni is a simple Byzantine church, with a cross shaped plan. It is currently used as a rehearsal room for the municipality theatre group, so it is normally not open. If you do gain access, however, there are some remaining frescoes that can be seen.
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.
