Among the many Russian Orthodox churches built around the turn of the century in various countries, St. Nikolaus Church in Vienna (Jauresgasse 2) stands out in particular in terms of its size, architecture and furnishings. This embassy church, built by Luigi Giacomelli according to the plans of the St. Petersburg architect Gregory Kotov, was built in the years 1893–1899. The church was consecrated on April 16, 1899. The church presents itself as a two-storey brick building in Russian-late Byzantine forms with colored glazed terracotta ornaments, crowned by five small towers with onion domes. The entire complex is divided into an upper and lower church, the execution of which differs in terms of the use of different materials. The portal of the church is decorated with a valuable Venetian mosaic bearing the inscription “Societa Musiva Veneziana”. A wide staircase leads to the upper church. Of all the interior furnishings from Russia, the so-called lkonostasis, the picture wall that separates the chancel from the large church room, deserves special mention. This picture wall can be found in Russian churches as early as the 13th century. The Russian church wants to symbolize the cosmos. The church interior is thought of as the universe, the altar in the east symbolizes paradise, the west wall hell and the middle between them earth. Since, according to the old Russian idea, the earth was thought to be square, we find the square layout in almost all Russian Orthodox churches. The iconostasis itself has three doors, two on the side for general use and one in the middle, the so-called “tsar’s door”, through which only the priest may pass (the highest priest in the Russian Church was the tsar). To the right of this is the icon of the Savior, to the left that of the Blessed Mother. The upper row of the iconostasis shows icons of 10 main festivals of the year, to the side of them are the icons of the Central cemetery and the opening of the new large cemetery in 1874, the five former municipal cemeteries no longer had any function and were closed. For a long time, little attention was paid to the cemetery, so it was able to retain its baroque character. In our century, in the years 1936/37, it was repaired under the direction of the architect Waldhauser and opened in October 1937. Since that time it has been an ideal connection between the park and its original function. The damage from the war has also been completely repaired. The cemetery is known worldwide for the Mozart grave. For Mozart, who was buried here on December 6, 1791 in a shaft grave, a grave of honor was later created in the central cemetery, where the original grave monument made by the sculptor Hans Gasser was placed. Mozart’s tomb (located roughly in the area where the composer was probably buried) was restored after the war by sculptor Florian Drouot. In 1958 another overhaul took place. The walk through the cemetery is a walk through Austrian cultural and intellectual history. Among the very prominent names are Madersperger, the inventor of the sewing machine, Albrechtsberger and Diabelli, and Josef Strauss. Of the actors, Therese Krones deserves a special mention. The name Basilio Calafati, so associated with the Viennese Prater, whose character of the “Chinese” made him famous, also appears here. But also statesmen like Count Cobenzl or inventors like Jakob Degen found their last resting place in the cemetery of St. Marx.
