Bedia Cathedral is a medieval Georgian Orthodox cathedral located in Bedia, in a disputed region on the Black Sea coast.
Bedia Cathedral was originally built at the close of the 10th century and consecrated in 999 on the behest of King Bagrat II of Abkhazians, who would go on to become King of the Georgians as Bagrat III and who was interred at the church after his death. The extant edifices, however, date back to the 13th-14th centuries and include a domed cruciform church, a belltower resting upon the northern narthex and the ruins of an old palace. The southern wall of the main church contains fragments of contemporary murals, including the portraits of Bagrat II and the representatives of the Dadiani noble family of Georgia.
In the Catholicate of Abkhazia, Bedia was the centre of a diocese and the seat of a bishop. In the 17th century, services were ceased, but resumed from the second half of the 19th century onwards.
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.
