The Russian Orthodox Cathedral of the Dormition of the Mother of God and All Saints is the cathedral of the Russian Orthodox Diocese of Sourozh and holds various special services throughout the year. 


The building is a Victorian former church and contains a parish facing the north-east green of Ennismore Gardens, Knightsbridge, and a main façade facing the west that now looks extremely similar to the Basilica of San Zeno, Verona, since its remodelling in 1891. The church’s interior remains very similar to that of its Anglican forebear church designed by architect Lewis Vulliamy in 1848-1849. It also contains a monument erected in memory of the Royal Martyrs that were killed in 1918 by the Bolsheviks
