A handout picture released by Swiss architecture agency Herzog & de Meuron shows their project of a high rise building for the Porte de Versailles, a Paris district already hosting an main exhibition center. The 50-storey pyramid-like rising 180 meters would be the first skyscraper to be built inside Paris in 30 years. Paris mayor Bertrand Delanoe unveiled the project during a press conference today.
