Vollzugszentrum Klosterfiechten (VZK) is a correctional and therapeutic facility located near Reinach in the Canton of Basel-Stadt, Switzerland. Founded in 1987, the facility operates as part of the Justiz- und Sicherheitsdepartement Basel-Stadt JSD BS (Justice and Security department) and combines custodial enforcement with specialised forensic therapeutic support. The facility follows the ROS concept, introduced in 2018 in the German-speaking part of Switzerland, which structures reintegration through clear goals, regular evaluation, and a balance of care and security. VZK’s mission is to promote everyday skills, personal responsibility, and social reintegration for residents in a supportive and open environment.
