Hoa Lo is the best known of all the North Vietnamese prison camps. The French built it at the turn of the century. The PBS film, Return with Honor, recorded Lt. Ronald Bliss, while speaking about the prison's rusted shackles and ever-present rats, saying: "You could look at this place and . . . just hear the screams of about fifty years, because it was -- it is -- a hard place." Some of the most brutal torture of Americans took place here in specially equipped rooms.
