The interrogation room is a large room aboard the USS Enterprise-D that can be used for interrogations and hearings during courts martial or other judicial matters.
The room featured a circular raised dais with a single chair were the accused would be questioned. Interrogators would sit at either of two semi-circular desks placed at the base of the dais. Behind the desks, several rows of chairs could be arranged for observers if a hearing was open to the public.
In 2366, Romulan Alidar Jarok was interrogated by Commander William T. Riker and Counselor Deanna Troi in the room. (TNG: "The Defector")
One year later, the Klingon spy J'Dan and later Crewman Simon Tarses and even Captain Jean-Luc Picard were interrogated in the facilities. (TNG: "The Drumhead")
