Hoa Lo Prison is one of the most famous attractions and an important historical site in the French Quarter of Vietnam. For the Vietnamese people, Hoa Lo Prison symbolizes the spirit of resistance against colonialism and imperialism. Originally built by the French colonial government in the late 19th century, in 1896, Hoa Lo Prison was used to imprison Vietnamese political prisoners who were fighting for independence. During the Vietnam War, the North Vietnamese government used this prison to detain American prisoners of war. Many American pilots were imprisoned here, and it was known as "Hanoi Hilton J." Today, Hoa Lo Prison has been transformed into a museum, showcasing the prison's history and stories from those war and revolutionary years. The prison is surrounded by four-meter-high walls, indicating the heavy security it once had. The prison gate still retains the French sign from the French colonial era, which reads "Central Prison J." Visitors may wonder what the connection is between Hoa Lo Prison and huolu (firewood). Actually, the site of Hoa Lo Prison was originally a handicraft village, called Phu Khanh Village in Vietnam, specializing in the production of teapots, huolu (firewood), and other household items. Therefore, the place was named "Huolu Village." Later, the land of this village was seized by the French and converted into a prison. The handicraft village disappeared, and the prison that took its place became known as Hoa Lo Prison. Upon entering the Fire Prison, one encounters a series of static displays. The French had very specific requirements for the construction of this prison, including the strict requirement that all building materials be imported from France. The prison cost 33,000 francs to build, but in reality, the construction was not fully completed because many prisoners needed to be inspected before it was put into use.
