Møllergata 19 is an address in Oslo, Norway, where the city's main police station and jail was located.

The address gained notoriety during the German occupation from 1940 to 1945, when the Nazi security police kept its headquarters here.

Based on the drawings by Jacob Wilhelm Nordan, construction for the complex started in 1862 and was finished in 1866.

[1] Facing Youngstorget (which then was called Nytorvet), was the police station and courtrooms; behind these was the jail.

[2] Immediately upon arriving in Norway, the German army commandeered Møllergata 19 for its own purposes, and the first prisoners were British subjects suspected of being clandestine agents, arrested on 10 April.
