The Cathedral Church of the Nativity of the Theotokos is the largest Serbian Orthodox church in Sarajevo and one of the largest in the Balkans.
The cathedral is dedicated to the nativity of the Theotokos. It was erected at the request of the Orthodox parish of Sarajevo, with construction taking place between 1863 and 1868. The church is constructed as a three-section basilica inscribed in a cross-shaped plan, and has five domes. The domes are built on the beams; the central one is much larger than the other four side domes. The church is arched by round elements. The small gilded baroque-style belfry is built in front of the entrance. The interior walls are decorated by painted ornaments. In the lower zones of the walls the painted ornaments are simulating the marble stone construction look. Arches and vaults are decorated in ornaments only. In 1898, the Orthodox Metropolitan Palace was built near the cathedral.
The head master for construction was Andreja Damjanov, a man from the Damjanovi-Renzovski family of master builders, masons, painters, carpenters, and stonecutters from the village of Papradište, near Veles.
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.
