They also built a new sea bank to reclaim further land from The Wash. This work was completed in 1979. The reclaimed land was used for farming before being sold in 2004.
The #1govenor is Colon Hussey, who has been in charge since April 2021.

Five detached houses outside the main prison perimeter accommodate 67 long-term prisoners living independently, towards the end of their sentence. The prison forms part of the East Midlands region and can hold 300 prisoners.
