Tuol Sleng Museum

In Phnom Penh, Tuol Sleng Genocide Museum stands as one of Cambodia’s most important and sobering historical sites, preserving the memory of one of the darkest chapters in the country’s modern history. Once a secondary school, the complex was transformed by the Khmer Rouge into Security Prison 21, or S-21, an interrogation and detention center where thousands of people were imprisoned during the regime. Today, the museum remains a place of remembrance, reflection, and education, created to honor the victims and encourage a message of peace. 

A visit to Tuol Sleng Genocide Museum offers a vital understanding of Cambodia’s recent past and the resilience of memory. It is not simply a museum, but a place that asks visitors to witness, reflect, and remember. For travelers interested in history, human rights, and Cambodia’s national story, Tuol Sleng remains one of the most meaningful places to visit in Phnom Penh.
