To understand the full story of the French Quarter, you must visit the Hoa Lo Prison, which the French called Maison Centrale. Built in 1896, its name translates to fiery furnace, or hell hole, and it originally held Vietnamese revolutionaries struggling for independence. Later, during the Vietnam War, it became known to American pilots as the Hanoi Hilton. For a practical pointer, if you plan to enter the museum, it is open daily from 8 a.m. until 5 p.m. The entrance fee is approximately 50,000 Vietnamese dong per person. Afterward, for a perfect view of the district's charm, head to the intersection of Trang Tien and Phan Chu Trinh streets. The golden hour in the late afternoon offers the most spectacular light for photography against the district's iconic yellow walls.
