The postcard is undated, but the various images on this card are shown on the Frith site as being taken in 1910: “Female Quarters”, “Female Entrance”, “Entrance”, “Male Quarters” and “The Terrace”. There have certainly been some changes since it was issued!
#78 – Drive Entrance, Pinewood Sanatorium, Wokingham, Berks
The Pinewood Leisure Centre, as it’s now known, is in Wokingham Without rather than in Crowthorne. I believe Pinewood Sanatorium was set up as a TB hospital for patients from London. In World War II it was a US Air Force hospital. In the 1970s the site began being used to house various locals sports clubs and groups. It now houses gym, judo, boxing, shooting, tug-of-war and model railways clubs (amongst others). It also has a mini railway and allotments.
