Justizanstalt Linz, Prison center in Linz, Austria.

Justizanstalt Linz is a prison in Linz, Austria, located on Pochestraße. It is a regional court prison affiliated with the Landesgericht Linz and can hold 224 prisoners. Built between 1861 and 1864, it was then considered the most modern prison in the Austro-Hungarian Empire.

Justizanstalt Linz was built between 1861 and 1864 as the most modern prison of the Austro-Hungarian monarchy. In 1963 the former resettlement camp in Asten was purchased and attached as an outpost. From spring 2010 a forensic psychiatric centre ran there, and on 1 January 2019 the outposts became the independent Justizanstalt Asten.

The prison holds male and female pre-trial detainees from the Linz regional court district and female pre-trial detainees from the Steyr district; Steyr's own branch of Justizanstalt Garsten takes only men. Sentences of up to 18 months, substitute custodial sentences for administrative offences and financial penalties are also served here.

The prison is in the Pochestraße in Linz and is run by the Linz Regional Court. It holds men and women in pre-trial detention from the Linz court district and women from the Steyr district, plus sentences of up to 18 months. It has 224 places; on 30 August 2007, 365 of 373 places were occupied.

The prison was built between 1861 and 1864 and was considered the most modern penitentiary of the Austro-Hungarian monarchy at the time. Its former Asten branch, bought in 1963, became an independent institution on 1 January 2019.
