In 1959, the Russian Orthodox Church In Exile Cathedral was opened on Emperor’s Gate, London; it shut down in 1989. 11 years after the closure of the Cathedral on Emperor's Lane, the Cathedral of the Nativity of the Most Holy Mother of God and the Holy Royal Martyrs was opened. It was fully consecrated in 2005. Liturgy
