A World War II bunker in Hamburg has been turned into a hotel with a huge rooftop garden
During the reconstruction, the height of the building was increased from 35 to 58 meters, and the roof was converted into a city park that can be visited by anyone. Almost 23,000 plants were planted and observation platforms were made.
Inside, in addition to a hotel with a hundred rooms, restaurants, bars, a sports center and a concert hall will be opened as well
