Doncaster and Bassetlaw Teaching Hospitals, in partnership with the British Ironworks Centre, launched the Hearts for Doncaster campaign in 2022. The initiative was created to thank those who worked in essential roles throughout the COVID-19 pandemic or remember those who died during this time.

Members of the public were invited to donate £20 to embellish a metal heart with a written commemoration. The resulting structure stands as a 9ft tall and 18ft wide rainbow, currently decorated with around 700 hearts. These include tributes to NHS health and social care staff, messages of love to family and friends, or expressions of gratitude to other workers such as supermarket staff.

The proceeds raised have gone towards the Doncaster and Bassetlaw Teaching Hospitals Charity, spent exclusively on improving care and treatment.
