There used to be the Croydon General hospital in London road, Croydon . I went there in 1963 to have my foot xrayed and plastered, andmy brother also had an operation. Closed may years ago. As I understood it the workhouse was in Queens Road, became an 'old peoples' hospital in the 60's.My Grandfather spent his last days here. older family members recall it as the workhouse.
just for info Beckenham is just over the border in Kent.
