Tourists visit the Church of Ascension at Kolomenskoye park in Moscow, Russia, June 1, 2013. The church was built in 1532 on the imperial estate of Kolomenskoye, to celebrate the birth of the prince who was to become Tsar Ivan IV. As one of the earliest examples of a traditional wooden tent-roofed church on a stone and brick substructure, it has great influence on the development of Russian ecclesiastical architecture.
