Wrangel Tower is named after Field Marshal F. E. H. von Wrangel. He arrived in Königsberg in 1809 as commander of the privileged Cuirassier Regiment. Wrangel Tower was built in 1843 as part of a defensive bastion of the ring of Königsberg. Water tower is surrounded by a moat, thick brick walls and ceiling to within three meters. Within 30 years, in connection with the development of long-range artillery, the construction of the tower was considered outdated, and in the early 20th century tower Wrangel was put out of the fortifications and to April 1945 in any military action did not participate.
During the assault of Königsberg during the World War II the tower was used as a base defense. April 9, 1945 the tower was blocked by Soviet troops, received minor damage and surrendered with the remnants of the Königsberg garrison. Now the tower hosts wholesale stores, warehouses and cafes.
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.
