The Church of Mary Magdalene is a Russian Orthodox church located on the Mount of Olives, near the Garden of Gethsemane in East Jerusalem. The church was built in 1886 by Tsar Alexander III to honor his mother, Empress Maria Alexandrovna of Russia.
Church of Our Saviour on the Spilled Blood, St Petersburg, Russia. As a ghost, I am looking for a castle to haunt. What about this one? I know it isn't technically a 'castle' but look at its magnificent size! I think it would still be splendid to haunt.
The Russian Orthodox Church still uses the old Julian calendar, so Christmas celebrations take place 13 days after everyone else, on 7 January. If you're determined to celebrate the festive season twice, head there now.
