The Russian Church is a historic Russian orthodox church in Geneva. Grand Duchess Anna Fyodorovna, who resided in Bern and Geneva after she chose to separate from Grand Duke Constantine, gave funds to build the church in 1863; it was designed by David Grimm and completed in 1866 in the fashionable Les Tranchées neighborhood of Geneva. The Russian revival church with its Byzantine striped arches and gold onion domes underwent restoration in 1966.
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.
