Next-door was another prison, the Clerkenwell Bridewell for convicted criminals, built in around 1615.

During the Second World War part of the basement was altered to form a bomb shelter.

[2] Today, the site of the New Prison and the Clerkenwell Bridewell is occupied by the former Hugh Myddleton School (1893-c.1960), in Bowling Green Lane.

In 2009, the site was redeveloped by developer Sans Walk, and the vaults of the building (formerly used for the reception of prisoners, medical examination and baths as well as kitchens) were accessed by members of the IStructE History Study Group.
