<p>The proportion of older people in the prison system is steadily increasing, and with it the demands placed on correctional institutions with regard to accommodation and care. Compared to younger incarcerated individuals, older prisoners exhibit a significantly poorer state of health, with complex somatic and mental illnesses. This results in an increased need for medical and social care, which entails substantial costs for the correctional system. Nevertheless, the topic of “ageing in prison” has so far received little attention in public and academic discourse. Over the course of more than a decade, the “Agequake” projects have systematically examined the needs of older incarcerated people in Switzerland. In doing so, existing problems in the healthcare provision for older incarcerated individuals were identified, physical as well as mental health aspects were documented, and practical approaches to solutions were developed. In addition, a public engagement project was implemented to raise awareness among prison staff, healthcare professionals, and the general public of the challenges associated with ageing in prison. The present contribution summarizes the most important achievements of the research and public engagement projects.</p>
