The cathedral is the burial place of all Russian tsars from Peter I to Alexander III, with the exception of Peter II and Ivan VI. The remains of Nicholas II and his family and entourage were re-interred there, in the side St. Catherine's Chapel, on July 17, 1998, the 80th anniversary of their deaths. Toward the end of 2006, the remains of Dowager Empress Maria Feodorovna were brought from Roskilde Cathedral outside Copenhagen and reinterred next to her husband, Alexander III.
