Bronze knocker, Tothill Prison. In 1834, a new prison - Tothill Fields, Bridewell - was built north-east of Rochester Row, Westminster. It was designed by Robert Abraham as a panopticon, where the spoke-like rows of cells could be monitored from a central hub. From 1850 onwards, the prison was reserved for convicted female prisoners and boys under the age of 17. It was demolished in 1884.
