Inverness Cathedral is the seat of the Bishop of Moray, Ross and Caithness, ordinary of the Diocese of Moray, Ross and Caithness. The cathedral is the northernmost cathedral in mainland Britain and was the first new cathedral to be completed in Great Britain since the Reformation.
Bishop Robert Eden decided that the Cathedral for the united Diocese of Moray, Ross and Caithness should be in Inverness. The foundation stone was laid by the Archbishop of Canterbury, Charles Longley, in 1866 and construction was complete by 1869, although a lack of funds precluded the building of the two giant spires of the original design. The architect was Alexander Ross, who was based in the city. The cathedral is built of red Tarradale stone, with the nave columns of Peterhead granite.
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.
