Site: Millbank Prison - Atterbury Street (1 memorial)
SW1, Atterbury Street
There are two (well, we've only found two) of these giant bollards commemorating Millbank Prison and the transportation of prisoners. See nearby Riverside Walk for the other one. You'll have noticed that this neat courtyard also hosts Henry Moore's 'Two piece reclining figure No.1, 1959'.
Site now occupied by Chelsea College of Arts.
