Lloyd the Graffiti Artist created the artwork for St Caradog Ward at Withybush Hospital, funded by donations to Hywel Dda Health Charities.
The Pembrokeshire artist, who has been painting since 1998, is renowned for his work capturing the county’s history and natural beauty.
He creates unique paintings using spray paints and has collaborated with schools and youth organisations across Pembrokeshire.
Aileen Jakeman, occupational therapy technician, said: “We are very grateful that charitable funds have enabled us to fund Lloyd to create the fantastic artwork.
“The murals have completely transformed our garden.
“Colour can have such a powerful impact on our moods, feelings and behaviours, social studies have shown that colours created in the right environment can have a positive impact on health and mental well-being.
“The artwork can now benefit our service in many ways: distraction when a patient is overwhelmed by anxiety, a talking point when dealing with emotions and depression, and a peaceful environment for group work and socialising.”
Nicola Llewelyn, head of Hywel Dda Health Charities, the official charity of Hywel Dda University Health Board, said that the support of the community helps the charity to provide services above and beyond the usual NHS provision across west Wales.
