At the back of the cathedral right side is an addition for the Chapel of St. Catherine and tombs.

On the left side of the cathedral are the remains of Empress Maria of Denmark (Princess Dagmar there), wife of Tsar Alexander III and mother of Nicholas II, the last Russian Tsar. Her remains were returned to Russia from Denmark in 2005 to finally fulfill her desire to rest next to her husband.

We see another altar to the left of the main altar and exit by a side door into museum exhibition spaces.
