Russian Orthodox Cathedral of the Most Holy Trinity, San Telmo
The Russian Orthodox Cathedral of the Most Holy Trinity stands in the San Telmo district of Buenos Aires, facing Lezama Park. Its 17th-century Muscovite style makes it unmistakable, and it is one of the most surprising hidden gems in Buenos Aires.
Five blue domes with golden stars rise above the low houses of San Telmo. The design was drawn in St Petersburg, and this church was the first Orthodox temple in all of South America.
The history of the Russian Orthodox Cathedral of the Most Holy Trinity
By the 1880s Argentina was home to many Orthodox Greeks, South Slavs, Arabs and Romanians, yet the country did not have a single Orthodox church. In 1887 the faithful of Buenos Aires sent a petition to Tsar Alexander III, and in 1888 the first Orthodox church in South America was set up: two small rooms in a house on Calle Talcahuano, next to the Russian imperial mission. The first liturgy was celebrated in January 1889.
In 1891 the priest Konstantin Izrazcov arrived as parish priest and pushed for a church of its own. The plot was bought at the end of 1894, and in 1897 he travelled to Russia to gather donations: some people gave money, others icons, crosses, chalices, vestments and fabrics. Known donors include the Dowager Empress Maria Feodorovna and St John of Kronstadt.
The design was drawn up in St Petersburg by Mikhail Preobrazhensky, architect of the Holy Synod of Russia, and the building was adapted and built in Buenos Aires by the Norwegian-born architect Alejandro Christophersen, who was based in Argentina, together with the engineer Pedro Coni. The foundation stone was laid in December 1898 and the church was consecrated on 6 October 1901 in the presence of President Julio Argentino Roca and the diplomatic corps.
The result is a church inspired by 17th-century Muscovite architecture, set on a plot of about 717 square metres, 16 metres wide and 44 deep. Its five blue onion domes with golden stars, crowned by Orthodox crosses held by chains, stand out above the low houses of the neighbourhood. On the front, a bronze bas-relief reproduces the façade of the church, and on the sides there are two murals, one of them devoted to the Baptism of Rus. The church proper is on the first floor and is entered through a richly decorated door on the left of the façade; the altar faces east, and among the icons the one of the Holy Trinity, which gives the church its name, stands out.
In the early decades of the 20th century the parish was far more than a place of worship: it ran a consumer shop, a shelter for people in need, a free reading room, a choir and an amateur drama group. In 1911 a loan made it possible to build an apartment block on Calle Europa, today Carlos Calvo, whose income gave the community almost a century of independence. Konstantin Izrazcov died in 1953 and, by special permission of President Perón, was buried in the church itself. Today the building is a National Historic Monument.
