At the prison

I admit that these aren’t the most pleasant places but I think that there are opportunities to take interesting pictures in such places. I’m aiming for pictures taken in facilities that are closed down but are open for public (or urban explorers) to visit, such as prison museums. NO pictures from active prisons. Cells and dungeons, corridors, cantinas, showers and...attributes ;) Can be from prehistoric times, over the medieval times, WWI and II until present time. Pictures with prisoners, wardens or other staff members who are recognizable are not allowed except when it concerns instructive/educational material which is displayed at the facility. No political statements and please keep it respectful. ===> Tell us the name of the place where the photo was taken <=== (no place name will result in a DQ.)
