The Dark History of the Prison of Nations

The casemates were not originally built to be a prison. They were designed in the 17th century as a military hideout. Soldiers used these vaulted rooms to store gunpowder and supplies. They also provided shelter during long sieges of the city. The thick brick walls were nearly impossible to penetrate.

In 1783, Emperor Joseph II changed the castle's purpose. He decided to turn the casemates into a high-security prison. It soon earned the nickname "Prison of Nations." This was because it held revolutionaries and political rebels from across the Habsburg Empire. It was known as the harshest jail in Europe at the time.

Life inside these walls was incredibly brutal. Prisoners were often chained to the walls in total darkness. The damp conditions and lack of light made survival difficult. Today, the museum displays help tell these stories. You can learn about the various groups who were held here over the decades.

During World War II, the Gestapo also used the castle. They kept many Czech patriots and resistance fighters here. This long history of suffering makes the site a significant place for reflection. It is an essential stop when looking for things to see in Brno.
