The Cathedral of the Holy Trinity is the only Orthodox church in Buenos Aires. By the end of the 19th century, the city was home to a large number of Orthodox Arabs, Romanians, Greeks and Slavs, who appealed to the Russian Emperor Alexander the Third to build the church. After a few years, the parishioners of the church by national composition became exclusively Russian, as the Arabs and Greeks built their own parishes.
Initially, the church was assigned two rooms in a small mansion in the city centre. Later, a separate Orthodox church was built, designed by Argentine architect Alejandro Christophersen. The cathedral was decorated in the style of 17th century Russian churches.
The building is two-storey: on the ground floor there is a school, and on the ground floor - the church. The painting of ceilings, columns, domes, arches and all the ornamentation was done by an artist from Italy - Matteo Casella. There are 2 side chapels in the church - the side chapels of St Mary Magdalene and St Nicholas the Wonderworker. In the church there are the following icons-paintings: "The Last Supper", "Holy Trinity", "Transfiguration of the Lord", "Ecumenical saints" and others. A distinctive feature of the church is the porcelain iconostasis and holy relics donated by the Athonite elders.
At the beginning of the 20th century a shop, a free reading room, an amateur choir, a shelter for the needy, a cultural and educational circle were opened at the church. Currently, the Cathedral of the Holy Trinity opened a school, services are held on Saturdays, Sundays and holidays. Entrance to the church is free for Orthodox and local residents, as well as for tourists.
