Prison of Anemas The Prison of Anemas (Turkish: "Anemas Zindanları" ) is a large Byzantine building attached to the walls of the city of Constantinople (modern Istanbul, Turkey). It is traditionally identified with the prisons named after Michael Anemas, a Byzantine general who rose in unsuccessful revolt against Emperor Alexios I Komnenos (r. 1081–1118) and was the first person to be imprisoned there. The prison features prominently in the last centuries of the Byzantine Empire, when four Byzantine emperors were imprisoned there.
