The Lutheran church of St. Catherine was built between 1788-1793. It is named after Empress Catherine II, who donated 28 000 silver roubles to the construction. The classicist-style building is a one naved church with large arched blind windows.
In the course of renovation in 1879, the spire received a new helmet and a clock with four faces. Supposedly architect Christoph Haberlandt made the design of the church. The altarpiece depicts Christ on the cross and is subject to protection by the state as a heritage of culture.
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.
