The Chernobyl Sarcophagus is one of the most extraordinary structures ever built by humanity, completed in a record time of 206 days to isolate the destroyed Reactor 4. This monumental facility stands as a testament to the incredible effort of 90,000 people who faced unprecedented challenges in one of the most radioactive environments on Earth.
In this episode of Chornobyl Uncharted, we uncover the remarkable engineering feats, bold decisions, and untold stories behind its construction. From daring initial designs to the final assembly of colossal beams, walls, and roofs, we’ll take you step by step through the creation of the Shelter Object and reveal why it remains a defining achievement of its era.
Discover why an entire train was buried inside the structure, how massive DEMAG cranes were deployed, and the secrets of this colossal project. Featuring rare images and detailed explanations, this episode explores one of the most enduring legacies of the Chernobyl disaster.
