The House of Soviets is a building located in the city of Kaliningrad and was built on the original territory of Königsberg Castle. The castle was severely damaged during the bombing of Königsberg in World War II. Following the war, as the city came under the control of the USSR, the site of the castle was redeveloped as part of the reconstruction of the city. Construction began on the House of Soviets in 1960, and was intended to be the central administration building of the Kaliningrad Oblast.
Continuation of development was stopped in the 1980s after the Regional Party Committee lost interest in the project and cut off funding. The building was left unfinished for many years, and earned notoriety as one on the worst examples of post-war Soviet architecture.
In 2005, for a visit by President Vladimir Putin, the exterior was painted light blue and windows were installed. However, the interior remains unfinished and unusable. A German consultant has recommended tearing down the entire structure and building anew as cheaper and safer than attempting to repair and finish the existing shell.
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.
