Sleeping in the “hole”: A luxury hotel in an open pit mine is opening near the Chinese metropolis of Shanghai. The 18-storey building was built into the walls of a huge quarry, 16 of the floors are below the surface of the earth, two of them even under water.
Due to the location within the abandoned mine, the building is considered to be environmentally friendly. Using solar energy and geothermal energy, the hotel also wants to produce enough energy to meet its daily needs.
