Hi Golfy,
Selly Oak Hospital is in Raddlebarn Road, Selly Oak, Birmingham. Its now part of the University Hospital Birmingham Foundation Trust and will be moving to a new, state of the art (a bit too futuristic for my liking!!) building on the Queen Elizabeth Hospital site in Edgbaston. (I spent 25 years working at Selly Oak as a medical secretary and moved to Lincoln 3 years ago). You can see the new hospital if you type a search for University Hospital Birmingham. I loved the old building at Selly Oak, which was, if I remember correctly, the Kings Norton Workhouse prior to becoming a hospital. Sometimes it still felt like a workhouse!!!
Hope this is helpful.
