The 25-storey Cosmos is located between Prospect Mira, Kosmonavtov Street and Yaroslavskaya Street at a site which once hosted 1-storey residential buildings demolished in early 1970s. According to the original idea of the architects, the semicircular building of the hotel echoed the semicircle of the main entrance to the Exhibition of Economic Achievements and closed the axis of the main avenue of the exhibition, but it was not possible to place Cosmos at the intended location due to the close proximity of Kosmonavtov Street and Prospect Mira. As a result, the hotel was shifted to the northeast, and its massive volume and centric composition set the neighborhood a new axis of symmetry.
The building was innovative in many ways for the USSR: 3-chamber double-glazed windows were used here for the first time, the heating control system relied on data from numerous sensors on the facade of the building, key cards were used to enter the rooms and for payments at the hotel, besides, Cosmos had the very first bowling alley and a quasi-automatic telephone station for conference calls in Soviet hotels. Technical innovations in construction and metal cladding, combined with scale, made the hotel resemble high-tech style architecture.
In 1990, the area between Cosmos and Prospect Mira received the name of the French military and statesman Charles de Gaulle. Fifteen years later, an 8-meter monument to de Gaulle by sculptor Zurab Tsereteli and architect Alexander Kuzmin was solemnly erected on the square in the presence of the acting presidents of Russia and France, Vladimir Putin and Jacques Chirac.
