Built between 1633 and 1636 to commemorate Russia's liberation from Polish occupation during the Time of Troubles, this church was purposely blown up in 1936, at the beginning of a planned remodeling of all Kitai Gorod that was to help usher in a new industrial era. The centerpiece of the area was to be a monumental House of Industry, but neither the House nor the plan ever came to fruition. The current cathedral is a replica, rebuilt and fully restored in 1993. Its salmon-and-cream–painted brick and gleaming gold cupolas are now a colorful magnet at the northeast corner of Red Square, between the Historical Museum and GUM. Inside and outside hang icons of Our Lady of Kazan; every inch of the impressive interior is covered in frescoes and whorled floral patterns. Many worshippers visit throughout the day.
