A glass-walled stupa on the grounds of Wat Phnom containing the skulls and bones of an estimated 5,000 Cambodians killed during the Khmer Rouge era. Smaller and less visited than the memorial at Choeung Ek, but its presence in the centre of the city — under the temple from which Phnom Penh takes its name — makes the encounter unusually direct.
The remains were exhumed from mass graves in the 1980s and brought here in a quiet act of public commemoration. Pay your respects, walk the surrounding park, and continue up the hill to the wat itself.
