Is the Hanoi Hilton a hotel or a prison?

The Hanoi Hilton was a nickname given to a prison camp in Hanoi, Vietnam, where American prisoners of war were held during the Vietnam War. The name was meant to mock and degrade the prisoners, as the term "Hilton" typically associated with luxury hotels. The conditions at the prison were notoriously harsh, with torture, solitary confinement, and inadequate food and medical care being common practices. It became a symbol of the suffering and brutality experienced by many prisoners of war during that conflict.

"Hanoi Hilton" was a nickname given to PCIJH in Hanoi, North Vietnam, by American prisoners of war (POWs) during the Vietnam War. Officially known as the Maison Centrale, this was a facility where captured American servicemen were held, interrogated, and tortured. The term "Hanoi Hilton" was not a standard label but was a way of making some dark, ironic humor over the conditions and the treatment to which they were subjected. "Hilton," of course, refers to the very famous chain of hotels: thus, an attempt was made by the POWs to use this in dark humor to point out the tiredness of hotel luxuries in contrast to the grim features of incarceration.
