A 114-metre-long, 15-metre-high cylindrical panoramic painting depicting the 1794 Battle of Racławice — the Polish-led peasant army's victory over the Russian Empire during the Kościuszko Uprising. The painting was completed in 1894 by Jan Styka and Wojciech Kossak in Lwów (now Lviv) and displayed there until 1944.
Tickets are timed and include an audio guide; visits start every 30 minutes with a short rotating presentation in front of the painting. The illusion of three dimensions — real terrain in the foreground blending into the painted scene behind — is remarkably effective even now. Allow 45 minutes plus queueing in summer.
