During my little absence in virtual word I was in Berlin. The city that has the darkest history in the last century. Even with little knowledge of the past the spirit of bad incidents accompanied me through the city. The famous names of modern architecture such as Peter Eisenmen and Daniel Libeskind left their marks following the history of Berlin. There is also an influence of Bauhaus and its directors Walter Gropius and Ludwig Mies van der Rohe in the architecture of the city.
