Unpaid carers are people who care for family members or friends with disabilities, chronic illnesses, and progressive neurodegenerative conditions. Contemporary carers have higher than average rates of physical and mental health problems. This chapter provides an overview of an interdisciplinary collaboration which brought together archaeologists, historians, anthropologists, social care researchers, charities, and community arts organisations to co-create a proposal for research exploring cultures of unpaid care. Central to the project from the outset was the active participation of contemporary caregivers, and organisations that work with unpaid carers, to ensure the proposed research was both informed by, and beneficial to, those with lived experience of care. The project culminated in a public consultation which provided an opportunity for a diverse range of carers across the South-West of England to respond to the initial research ideas. Inspired by this engaged research, Devon artist Leo Jamelli was commissioned to produce a new work, Invisible Carer, a large-scale animated light installation that was projected onto the ruins of the St. Catherine’s chapel and almshouses in Exeter. This chapter discusses a best-practice approach to co-production of research in bioarchaeology adapted from current National Institute for Health and Care Research guidelines.
