Tuol Sleng Genocide Museum (S-21)

113 Street and 350 Street, Phnom Penh, Cambodia

The Basics

The museum offers a dark and disturbing window into the atrocities committed by the Khmer Rouge. The interrogation rooms have been left as they were in 1977, and photographs of the regime’s victims are on display, along with rusting tools of torture. The museum suggests visitors should be at least 14-years-old as the exhibits are too disturbing for most children. Visitors are expected to behave respectfully during their visit.

Tuol Sleng is a common stop on Phnom Penh city tours, which typically also include the Royal Palace, the National Museum of Cambodia, and Wat Phnom. For a more in-depth look at the horrors perpetrated by the Khmer Rouge, book a Tuol Sleng tour that includes a trip to the Killing Fields of Choeung Ek, south of the city, where S-21’s 17,000 or so victims met their deaths.

A must.
A must. Terribly moving, learning the history of the country of the past fifty years in the places where the atrocities happened, leaves a mark on you. I've done several tours, but our guide here, Chesda, was the best of all. Excellent English, knowledgeable, sensitive, caring.

The Killing Field and Toul Sleng Genocide Museum Tour
I recommend this tour. It was very informative but also gave time for those on the tour to experience each site personally. Chesda was my tour guide and was very knowledgeable about the locations and events as well as sharing information about Cambodia and providing recommendations for tourists.

Heartbreaking Tour

The Killing Field and Toul Sleng Genocide Museum (S21) Tour
The S21 Prison was a grim memorial to the thousands of innocent Cambodians who were shackled, tortured, and summarily executed. It was a heartbreaking exhibit of the depths of human cruelty. Meeting survivors was very inspiring. The Killing Fields was a good introduction to the atrocities committed by the Khmer Rouge. Our guide Baboon provided a very personal touch to the tour, having parents who were deeply affected during this era. A must see in Cambodia.

Important and sobering experience

The Killing Field and Toul Sleng Genocide Museum (S21) Tour
Both places definitely a must see in Phnom Penh. It was a very sobering but nonetheless extremely important experience. Our guide, Amon (not sure if that's how you spell it), was fantastic - very knowledgeable, great English, and gave what is already a tragic story a personal touch that made the tour even better. Definitely would recommend!
