The construction of the church celebrated the 50th anniversary of the reign of Emperor Franz Joseph I of Austria.
The four-bay, basilica-like brick building was intended as a garrison church; designed in the Rhenish-Romanesque style, its three red-tiled towers are visible several kilometres away.
The Art Nouveau-style Elisabethkapelle (Elizabeth Chapel) is located on the left of the church next to the choir.
