The Cathedral of the Kazan, in the northwest corner of Red Square. The original church was erected as a shrine in the early 1630s to mark the city's liberation from the Polish aggressors by the Russian people's volunteer army. In 1936, when Red Square was being prepared for holding the military parades of the Soviet Union, Joseph Stalin ordered the square cleared of churches and it was demolished. The cathedral was reconstructed in 1993. (06/06/1999)
