 The workhouse became the St Asaph Public Assistance Institution in 1930 and it joined the National Health Service as the H.M. Stanley Hospital, named after its famous student, in 1948.After the health board found that the hospital would need substantial refurbishment work to restore it to a status that was fit for purpose, services at the hospital were transferred to other hospitals, including a new eye unit at Abergele Hospital and it closed in April 2012.The site remains the headquarters of the Welsh Ambulance Service.
