Near the train station there is a small temple, which can hold up to 300 people. This five-domed church with a high turret, which houses the bell was consecrated in the name of Saint Olga. For more than a hundred years, the temple used by the Orthodox Church in the Czech Republic. It was built for the needs of Russian vacationers who performed in Franzensbad from several months to half a year, adjusting their health. The cornerstone of the future of the sacred building was laid in 1881. The construction of the temple lasted for 8 years. Only in 1889 it was held the first service.

The architect of the church of St. Olga was elected local mayor and at the same time a talented specialist Gustav Viderman. Before the construction of the temple he had built the Orthodox Church in Karlovy Vary and some other buildings of the region. Education person who also traveled a lot, Viderman developed a project based on the achievements of the architect A. Aubert. Perhaps that is why the Church of St. Olga recalls temple, built in the Moscow region on the estate Rukavishnikov - the brainchild of Auber.

When the Nazis invaded Franzensbad, they took the building of the Church of Saint Olga for storing ammunition. This surprised city officials, who appealed to Metropolitan Seraphim. Only his intervention helped to protect the church from inappropriate use. Unfortunately, even such high patronage of the church hierarchy does not help to save the unique paintings on the walls. Therefore, after the war, during the reconstruction of the temple of all the internal frescoes were created anew.

The Church of St. Olga is open daily.
