Santísima Trinidad Russian Orthodox Church

This church in the 17th century Muscovite style opened in 1904. The original project was designed by the architect of Russia's Holy Synod, Mihail Preobrazensky, and later adapted in Buenos Aires by Alejandro Christophersen, who designed many other buildings in the city, including the Palacio San Martín in Retiro. Each of the church's blue domes is topped with a cross facing East and supported by chains, as is the custom in Russia. The facade shows three biblical scenes, and the frontispiece features a mosaic image of the holy trinity brought from St Petersburg
