Over the past four decades, restorative justice has developed within prison settings across much of Europe. When introduced into closed institutions, restorative justice must be understood not only as a set of practices but also as a process shaped by the prison’s structural, cultural, and relational dynamics. Prisons are not neutral spaces — they influence how harm, accountability, and healing are experienced by all involved.
Restorative justice emphasises the repair of harm through inclusive processes that engage victims, offenders, and communities. In the context of imprisonment, this means recognising both the potential for healing and the barriers created by institutional power dynamics, isolation, and systemic violence.
The European penal landscape has significantly evolved. Traditional large prisons have been complemented by diverse forms of closed institutions: small-scale detention facilities, halfway and transition houses, institutions with electronic monitoring, and forensic psychiatric units. This shift calls for a broader understanding of what “imprisonment” entails — including how confinement can impact individuals' identities, relationships, and prospects for reintegration.
At the same time, the prison population has changed in both size and composition. Though numbers have fluctuated — 483,600 prisoners in the EU in 2022, down from a peak in 2012 — there are growing challenges: overcrowding, increasing numbers of short-term sentences, limited access to conditional release, and the rise of complex social issues such as radicalisation and online criminality. Nearly 27% of inmates are foreign nationals, adding layers of linguistic and cultural complexity to restorative efforts.
These realities demand that restorative justice approaches remain flexible, context-sensitive, and grounded in a holistic understanding of harm. To be effective, restorative work in closed settings must address the multiple layers of impact — personal, relational, institutional, and societal — that define modern imprisonment.
