The Eurosky Tower, designed by Franco Purini and Laura Thermes in the centrality EUR-Castellaccio in Rome started from the union of two symmetrical towers, in many respects autonomous: a dolmen that on the roof performs liberating and propitiatory exploits. The ontogeny of Eurosky, recapitulates phylogeny of a series of projects delivered to the history of contemporary architecture. In the first place the constructivist Horizontal Skyscrapers for the center of Moscow, designed in 1924 by El Lissitzky, also called "Irons for the clouds". But in it is also possible to find futurist images by Antonio Sant'Elia, those of Hugh Ferriss, as well as the ones of BBPR of the Velasca Tower.
