The purpose of this report is to give an overview of the current situation on the ground when it comes to visitors’ access to detention centres in Europe. We collected and analysed information based on the direct experience of JRS country offices in the abovementioned 14 European states. In those countries where JRS is currently not visiting, the information provided is based on past experience (when this is the case, reference to a certain country will be marked with *). In some countries, JRS only visits one or a few of the existing detention centres, so we do not see the full picture of detention in Europe. However, the information at our disposal already offers sufficient material for reflection on good practices and room for improvement.
