The church was consecrated on September 15, 1903, by the Bishop of Warmia, Andreas Thiel.
The architectural style is characterized as neo-Gothic with distinct polychromy and brickwork patterns.
During the post-WWII period, the church underwent various interior renovations to restore its original liturgical character.
The building was designed by Fritz Heitmann, a prolific architect responsible for numerous churches in the Warmia-Masuria region.
The Kościół Rzymskokatolicki pw. Najświętszego Serca Pana Jezusa in Olsztyn is a significant neo-Gothic structure constructed between 1901 and 1903. Designed by architect Fritz Heitmann, the church features a prominent 68-meter high tower that serves as a focal point in the city skyline. It was originally built to serve the growing Catholic population of Olsztyn (Allenstein) during the Prussian era. The interior retains historic stained glass windows and liturgical elements that survived 20th-century conflicts. The red brick facade showcases typical late-19th-century German neo-Gothic ornamentation. It functions as an active parish church located within the city's historic district.
