The Church of St Aeddan, Bettws Newydd, is a fifteenth-century church of twelfth-century origin. The interior contains perhaps the most complete rood arrangement remaining in any church in England and Wales. The rood screen, loft and tympanum are all in situ. The Royal Commission on the Ancient and Historical Monuments of Wales considers that the screen is 'most remarkable' and 'probably unique in the British Isles'.
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.
