Justizvollzugs- und Sicherungsverwahranstalt Diez

The Justizvollzugs- und Sicherungsverwahranstalt Diez is a correctional institution in Diez, Rhineland-Palatinate. The compound consists of multiple structures with central control points from which the building compartments can be observed.

The facility opened at its current location in Freiendiez in 1912 after operations had originally taken place in a castle starting in 1778. The relocation followed six years of construction work.

The name reflects its administrative function as a place of judicial enforcement. Visitors can observe the functional architecture designed with security and order in mind.

Access to the facility is limited to specific times and under certain conditions, as it is an active correctional institution. Visitors should check in advance about visiting hours and required documentation.

The institution has a long connection to local history and reflects different phases of correctional practice in Germany. The shift from a historic castle to a purpose-built facility shows the evolution of prison standards over more than a century.
