Lepoglava prison, Maximum security prison in Lepoglava, Croatia

Lepoglava Penitentiary is a working maximum-security prison in Varaždin County, northern Croatia, run by the Ministry of Justice, not a museum. It occupies the buildings of a former Pauline Fathers' monastery that the authorities converted into a penitentiary in 1854. A memorial to the prison's victims was erected in front of it in 2005.

Lepoglava prison was established in 1854 in a monastery formerly owned by the Pauline Fathers, which the authorities converted into a penitentiary; part of the order's property there was returned to the bishopric only in 2001. It was subsequently used by Austria-Hungary, the Kingdom of Yugoslavia, the Independent State of Croatia and communist Yugoslavia. In 1878 warden Emil Taufer introduced the Irish rehabilitation system and opened workshops for penal labor, with literacy classes for younger offenders.

The prison is named after Lepoglava in Varaždin County, and its buildings began as a Pauline Fathers' monastery, part of whose property was returned to the bishopric only in 2001. In 1878 warden Emil Taufer introduced the Irish rehabilitation system and opened workshops for penal labor, with literacy classes for younger offenders. Among those held here were Josip Broz Tito, Moša Pijade and, after the Croatian Spring, Franjo Tuđman.

Lepoglava Penitentiary is an active maximum-security prison run by the Croatian Ministry of Justice, not a museum, so there are no visitor tours of the cell blocks or workshops. The complex occupies the former Pauline monastery in the town of Lepoglava, Varaždin County. A memorial to the prison's victims was erected in 2005 and can be seen from outside.

In July 1943, partisan forces carried out a coordinated raid that freed around 800 prisoners in a single operation. That action is still considered one of the largest prison liberations in the region during the Second World War.
