St Cwyfan's church was in existence by 1254 and was enlarged in the 14th and 15th centuries. The building later fell into disrepair, and in the 19th century parts of the church were demolished. By 1891 the surviving part was roofless, so an appeal was launched which paid for the building of a new roof. In about the 1970s all the windows were restored, but now the building is deteriorating again and a new restoration appeal has been launched.
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.
