The old prison of Basel, popularly known as „Schällemätteli", is located in Spitalstrasse 41 and started operating in 1864. The cross shaped building and even its chapel have been constructed according to the principles of panopticism for keeping the convicts under permanent observation. Men and Women were imprisoned in Schällemätteli. Under its full capacity it occupied up to 144 convicts. The prison was closed down in 1977.
