[1][4] The church is named after St. Florian, the patron saint of professions associated with fire, such as firefighters, steelworkers, chimney sweeps, potters and bakers.

[1] St Florian's is the cathedral church of the Roman Catholic Diocese of Warszawa-Praga and by order of the Holy See was raised to the rank of minor basilica in 1992.

[1] Over four hundred priests form the ministry in this diocese covering 1,274 square miles, divided into 160 parishes and serving approximately one million Polish Catholics.

[7] St Florian's is built in a Gothic Revival style distinguished by two twenty-story towers facing Aleja „Solidarności” (English: Solidarity Avenue), capped with bronze spires.

Over the entrances are mosaic depictions of Jesus Christ and the emblem of the first bishop of Warszawa-Praga diocese, Kazimierz Romaniuk, while the interior is decorated in red or white plaster and brick.
