Saint Bruno Church, Gothic Revival church in Chernyakhovsk, Russia.

Saint Bruno Church is a Gothic Revival structure featuring pointed arches, ornate wooden carvings, and large stained glass windows. The building displays the characteristic design elements typical of this architectural style.

Built in 1902 in Neo-Gothic style to designs by architect Friedrich Heitmann, the church replaced an 1865 chapel that had become too small for the growing parish. Its interior was finished only by 1912. Consecrated to Saint Bruno of Querfurt, patron of Prussia, it served 1,800 parishioners by 1927, about 4% of Insterburg's population.

The church is named after Saint Bruno of Querfurt, patron of Prussia, and in 2009 the parish marked the millennium of his martyrdom. Since 2000 an organ has stood in the building, so organ concerts are held there alongside services. Since 2005 a Franciscan monastery of Saint Maximilian Kolbe has operated at the church, and its friars also serve the Catholic community in Ozyorsk.

The building is located on Lenin Street and welcomes visitors interested in viewing the architecture or attending services. Those wishing for a guided tour should ask ahead about availability and accessibility.

The church was used as a military warehouse until the early 1990s, when its largely undamaged building was handed to the Ministry of Culture for conversion into an organ hall. A pipe organ was installed in 2000, and organ concerts have been held here alongside services since then.
