Reading prison is to close today, a month earlier than planned.
It is one of four prisons shutting under government plans to replace them with a super-prison.
The last of the 320 inmates at the Berkshire jail will be leaving later today.
The Prison Service said it was aiming to avoid compulsory redundancies by redeploying staff or offering voluntary early departures.
