This Ordnance Survey Map of Woking Invalid Convict Prison, Knaphill from 1870 clearly shows that our house (marked in red) was almost smack bang wallop in the centre of the prison complex.
Most images you see of the prison show the big block south-east of our house. We're not sure what the big block north-west of our house would have been.
I imagine there would have been a lot of curtain twitching going on during the prison's heyday watching all manner of convicts coming and going ;-)
