RESUMEN
The Lapinlahti Hospital initiative in Helsinki has transformed a disused psychiatric hospital into an open site for mental health promotion. The current study uses qualitative methods to explore how the initiative may promote population mental health. The phenomenological study comprised of data from 7 focus group including 28 participants. Resulting data were thematically analysed to articulate how the initiative supports mental wellbeing in different ways. Mental health benefits were categorized into three themes; mental health value, civil values and common values which were comprised of nine subthemes; paradigm shift, social inclusion, personal meaning, regeneration, ambience, stigma, sustainability, democracy and environment. Mental health promotion emphasises the impact of daily environments in which people live their lives. Results from this study support the use of broad based actions which promote different components of mental wellbeing simultaneously. Psychiatric hospitals may offer historically meaningful sites for such actions.
