Church of the Holy Trinity, Belgrade

From the beginning, the church's parish was in the ecclesiastical jurisdiction of the Russian Orthodox Church Outside Russia (ROCOR), headed until 1936 by Metropolitan Antony (Khrapovitsky) (on 31 August 1921, the Council of Bishops of the Serbian Church passed a resolution, effective from 3 October, that recognised Metropolitan Anthony's Temporary Higher Church Administration Abroad as an administratively independent jurisdiction for exiled Russian clergy outside the Kingdom of SHS as well as those Russian clergy in the Kingdom of SHS who were not in parish or state educational service; the THCAA (later, ROCOR) jurisdiction also extended to divorce cases of the exiled Russians[3]).

The main Russian shrine that was preserved in the church from the end of 1927 until September 1944 was the Kursk Root Icon.

[2] On 5 July 1931, Patriarch Varnava consecrated the Iveron Chapel in the New Cemetery in Belgrade,[6] which, while modeled on the Iveron chapel in the Red Square (destroyed in 1929), was in effect a church in its own right, complete with an altar, and served as a separate parish until 1945, when it was attached to the Trinity church metochion.

[7][8] In September 1944, shortly before the capture of Belgrade by the Red Army and Communist partisans, the parish was abandoned by the Karlovci-based administration of the anti-Soviet ROCOR (then headed by Metropolitan Anastasius (Gribanovsky)); its rector priest Sokalj, who in 1946 became a citizen of the USSR and in January 1950 had to leave for the USSR,[9] requested transfer to the jurisdiction of the pro-Soviet Moscow-based Russian Orthodox Church (Moscow Patriarchate) and in April 1945 joined the Moscow Patriarchate.

[14] The church was projected by the Russian architect Valery Vladimirovich Stashevsky, in the old, Novgorod-style of religious architecture.
