Mayan civilization predicted that 20 12 would be the end of the world, and now the prediction has been shattered, but Robert, the founder of the American rich Vivos project? Wisnier still believed in the existence of the end of the world, so in 20 15, he built a luxurious underground shelter in the village of Rottenstein, Germany, which was reported by the Daily Mail at that time and caused a heated discussion.

Robert? Wisnier's? Doomsday fortress? Originally a military barricade left over from World War II, it can resist nuclear explosions, earthquakes, biological viruses and other attacks after reconstruction.

Equipped with swimming pool, gym, cinema, church, bar, gym and other facilities, usually reserve at least one year's living materials, and equipped with outdoor helicopters.

The underground fortress covers an area of about 20,000 square meters, and the cost is about 65.438+0 billion dollars, of which the swimming pool in the fortress costs as much as 654.38+0.65438+0 million dollars. According to the design of the underground fortress, Robert? Visnir can also rent some rooms to other families, but the price is definitely expensive.

In each residential area of the fortress, there are three independent explosion-proof passages, each passage has a 40-ton hydraulic explosion-proof door, which can prevent the invasion of floods, toxic gases and so on after being closed, and a 5-kilometer-long tunnel is used for emergency escape.

Because the whole fortress is located on a hard rock structure, it has strong seismic performance, and the annual average temperature is kept at around 17 degrees Celsius. There are also independent domestic sewage treatment systems, air filtration systems and power plants in the fortress.

In America, there are many such doomsday fortresses, but not on the scale of Robert? For example, in Georgia, the developer transformed an abandoned missile bunker into a doomsday shelter, which was equipped with a kitchen, living room, bathroom and bedroom, and then sold it to the rich.
