The Belarusian Great Patriotic War Museum is a museum commemorating the German-Soviet War after the end of Nazi occupation sprung up even before the close of the war. The museum first opened shortly after the liberation of Minsk from the Nazi invaders, on 25 October 1944, making it the first World War II museum to open during the course of the war. It relocated to its current location in 1966. The museum staff also engages in historical research: particular areas include Belarusians in the Red Army, local anti-fascist and partisan activity, and the history of the Auschwitz death camp.
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.
