Leopoldov prison

The Leopoldov Prison is a Slovak state-operated penitentiary facility located in the town of Leopoldov. Initially a 17th-century fortress built to defend against Ottoman Turks, it was converted into a high-security prison in the 19th century, and it used to be one of the largest prisons in the Kingdom of Hungary under the Habsburg monarchy. In the 20th century, it became known for housing political prisoners and dissidents under the Stalinist regime, particularly the future Communist President of Czechoslovakia Gustáv Husák, who was imprisoned after an intra-party purge.
