The temple, though modest in size, holds profound importance due to its connection to the tragic Khmer Rouge period. It is most notable for housing a unique Buddhist memorial stupa, which displays the skulls and bones of victims who lost their lives under the regime’s brutality. The stupa stands as a somber reminder of the atrocities committed during the genocide, preserving the memory of those who perished. Visitors to Wat Thmey can reflect on the painful past while observing Buddhist rituals and offerings, offering a place for both remembrance and healing. Despite the dark history surrounding it, Wat Thmey represents hope and resilience, serving as a testament to Cambodia's enduring spirit and the importance of peace and remembrance in the face of past horrors.
