The prison is one of the most popular destinations for visitors to the island. During the wars against the French and Americans, many Vietnamese revolutionaries were detained and tortured in the prison, and some 4,000 lost their lives there. The prison has since been named a heritage site and its 12 sections restored. The restoration and decision to throw open the site to visitors is to benefit historical research and ensure that the heroic prisoners will never be forgotten.
