RESUMEN
There are well-established links between mental health and the environment. Mental illness is a global issue, and international policies increasingly focus on promoting mental health well-being through community-based approaches, including non-clinical initiatives such as therapeutic landscapes and the use of heritage assets. However, the empirical evidence-base for the impact of such initiatives is limited. This innovative study, known as Human Henge, used a mixed-methods approach to investigate the impact of immersive experiences of prehistoric landscapes on the well-being of participants with mental health issues. Uniquely, the study followed participants for a year after their participation in the project to explore the long-term impact of their experiences on their mental well-being. Findings highlight that, overall, participants experienced improved mental health well-being from baseline to mid- and end-of programme (p = 0.01 & 0.003), as well as one-year post-programme (p = 0.03). Qualitative data indicated the reconnection of participants with local communities, and with other people, in ways that improved their mental health well-being. These data highlight the effectiveness of using heritage as a means of improving the well-being of people with mental health issues.
