A vast white-and-gold Russian Orthodox cathedral built on the site of the Ipatiev House, where the Romanov family were executed in 1918. The lower church marks the cellar where the killings took place; the upper church is a soaring full-scale cathedral with bright iconography painted by the same workshop that worked on the Cathedral of Christ the Saviour in Moscow.
The cathedral is the city's main pilgrimage site and the most visited attraction. It is at its most striking on 17 July, the anniversary of the killings, when an all-night liturgy is followed by a procession to Ganina Yama, where the bodies were dumped.
