Coldridge Prison.
Coldridge Prison is the location of the first mission in Dishonored, and a mission in the upcoming DLC, The Brigmore Witches. Corvo Attano must escape Coldridge after being unjustly imprisoned there for the assassination of Empress Jessamine Kaldwin by Hiram Burrows, her usurper.
It features a cellblock (where Corvo is held at the beginning of the first mission along with two Bottle Street Gang members), an interrogation room, stocks (which can be viewed through Corvo's cell window, but not visited) and a drawbridge connecting Coldridge to Dunwall Tower.
According to Bethesda Softworks, Daud is tasked with infiltrating Coldridge to free the leader of the Dead Eels Gang in The Brigmore Witches.[1]
