Wat Samarong Knong

About 4km north of Battambang, Wat Somrong Knong was built in the 19th century on the site of a pre-Angkorian temple complex. The Khmer Rouge used the temple grounds as a prison, and it's believed that around 10,000 people were executed here. The complex today houses the gorgeous main pagoda and a mishmash of ancient ruins, glittery modern structures and memorials to those who perished here.
