Germany 🇩🇪

The "Forest Spiral" is a residential complex in the German city of Darmstadt, made in the form of a spiral. The buildings were designed by Austrian-born architect and artist Friedensreich Hundertwasser and are interesting because they have absolutely no right angles. 

The amazing original building has 12 floors and is made in the form of a horseshoe, on its roof there is a huge garden where residents can meet maples, beeches and other forest trees and shrubs, the total number of which exceeds 250 units.
