The Alexander Nevsky Cathedral is an orthodox church located in the city of Łódź. It was built during the period when Poland was part of the Russian Empire. It was constructed with the financial support from the local textile factory owners and the most prominent citizens who adhered to Judaism, Protestantism and Catholicism. The church was consecrated on 29 May 1884 by Archbishop Leontius the ordinary of Warsaw and Chełm Dioceses.
The orthodox church was designed and built in the Neo-Byzantine style in an octagonal shape. Stained glass windows and iconostasis, made from oak wood, with three doors are the main decorations of the church. Izrael Poznański, who financed the enclosure and fence around the church was also the founder of the iconostasis.
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.
