Built between 1924 and 1938 to a design by the acclaimed Poznań architect Adam Ballenstaed, this vast building supposedly resembles Rome's more famous Pantheon, and is one if the sightseeing highlights of any trip to Bydgoszcz. Capable of holding up to 12,000 people, the enormous interior is dominated by an immense neo-Classical dome, which at 65 metres dominates the surrounding skyline. Built with a repeating circular design, the church features two naves, one inside the other, supporting a dome containing over one hundred caissons, each intricately decorated with beautiful flower motifs. The main altar was designed by Wiktor Zin, complete with a representation of the crucifixion and an image of Saint Vincent after whom the church is named. Bursting with colourful mosaics and some exquisite stained glass, the church was badly damaged by fire by the retreating Germans in January 1945, and the reinforced concrete masterpiece wasn't fully restored until 2003. The church also is famous for its large choir, active in the city since 1928.
