The Pussy Riot Church

Formerly known as the cathedral of Christ the Saviour.

The original cathedral was built to celebrate Napoleon's withdrawal from Moscow. It was designed based off Hagia Sophia in Istanbul (I'll be there next week). Like many of the religious institutions, this church was destroyed in the Soviet era and has since been rebuilt.
