When going out of the gate arch of the Tsar’s courtyard in Kolomenskoye (ancient summer residence of Grand Dukes of Moscow and Russian Tsars), one suddenly sees a high-water bed of the Moskva River, a wide river stretch with fields and gardens disappearing over the horizon, a steep slope running down and in the center of all that and over it— an unusual, unique church, rising to the sky. It seems that the church is held by a light net of white stones with diamond facing. It is the Church of the Ascension built in 1532, a masterpiece of Russian and world architecture, inscribed in 1994 on the UNESCO list of World Cultural Heritage. The Church of the Ascension is a pearl of one of the largest museums in Moscow — MSUMR (The Moscow State United Art Historical-Architectural and Nature-Landscape Museum-Reserve). Since the museum was opened in 1926, its main purpose was to preserve and to study this architectural masterpiece. Today great attention is paid to its protection, restoration and use ( traditional church functions included).
