f. Hoa Lo Prison (Hanoi Hilton)
Hoa Lo Prison, literally translated as “Hell’s Hole”, is a prison built by the French around late 1800s and was named Maison Centrale. It was used by the French for political prisoners. During the Vietnam War, it was used for US Prisoners of War and was sarcastically known as Hanoi Hilton. This was also used as a base for the 1987 movie “The Hanoi Hilton.” Hoa Lo Prison was demolished in the 1990s except for the main gatehouse, which is still used today as a museum. Hanoi Hilton is completely different from the real Hilton Hanoi Opera Hotel.
