Plot twist: the casemates were not built as cells

The casemates are Špilberk’s celebrity dungeon, so here is the inconvenient fact: prison was not their original purpose. They were built in 1742, when Colonel Rochepin was helping turn the old castle into a modern Baroque fortress. These long vaulted spaces were military infrastructure. The northern casemates could shelter roughly 1,200 men; the southern side was used mainly for stores and military supplies. There were even ovens designed to produce bread on a scale of thousands. Only later, under Joseph II, were parts converted into an exceptionally severe prison. That change matters. A dark corridor can look as if it was born evil, but architecture does not have destiny. First: bomb-proof logistics. Then: incarceration. Same bricks, completely different human experience.
