Museum Panorama of the Battle of Racławice in Wrocław

You're standing by a round concrete building, right next to the National Museum in Wrocław. From the outside it doesn't look like much. But inside hangs the Racławice Panorama, a painting about a hundred and fourteen meters long and fifteen meters high, wrapped all the way around you in one giant circle. It's the oldest panorama in Poland, and one of the few survivors of this nineteenth-century crowd-pleaser.
