Open in 1904, it has a Muscovite style. Its full name is Russian Orthodox Church of the Holy Trinity. The original project was designed by the architect of the Holy Synod of Russia, Mihail Preobrazensky, and later adapted in Buenos Aires by Alejandro Christophersen, who designed many other buildings in Buenos Aires, such as the Palacio San Martín in Retiro.
It has some imposing blue domes that differentiate it from the buildings in the area. On its exterior it has a cross facing east and supported by chains, as is customary in Russia. The facade shows three biblical scenes and a mosaic image of the Holy Trinity brought from St. Petersburg.
