Other Although the hospital wasn’t opened until 1921, it was used as a military hospital in the First World War, and was known as the 4th Canadian General Hospital . In the Second World War a well renowned doctor, Harold Giles converted the private wing of the Park Prewett Hospital , into a 120-bed plastic surgery unit. This unit was known as 'Rooksdown House' which became a leading centre for plastic surgery within the UK .
Park Prewett also had it own railway which ran from Basingstoke station to the hospital it was built in 1913 and closed in 1954.
Having seen Park Prewett once before from the outside it was surprising how close the remaining parts of the structure are to the housing development which has replaced a lot of the outlying buildings and villas of the hospital.
The entry itself was rather eventful having nearly been seen just minutes out of the car! Diving out of the way and being quiet we managed to get in with no more problems.
The inside of the hospital was bare, most furniture being removed when the hospital closed. Wards seem to have been abandoned at different times with look newer and are fitted with partitions for patient privacy while others are open wards with ‘groovy’ wallpaper.
As with other former asylums service tunnels link the buildings together wandering along these we came to the water tower and boiler room, now home to pigeons and masses of their poo. 
For me the trip to the top was a little nerve racking especially when a chunk of the floor above came crashing past my head! The view from the top (what little I saw of it) was truly inspiring, it was just past dawn and the world was still asleep and here were we 140 ft ish above it all.
Next beckoned the Main Hall, not the most conventional way of getting in but managed to get a few pictures in the end.
After a short tour of the kitchens and getting a little lost again in the tunnels, breakfast beckoned and we left Park Prewett with hopes to return although a return visit will have to be a hurried one as this former Asylum was the first to be sold off by English Partnerships and will soon be turned into over 600 flats and houses.
