Preah Khan (“Holy sword”) is a rather labyrinthine temple complex, built under Jayavarman VII in the late 12th century to commemorate victory over the Chams. It serves as the core of the Buddhist temple complex that includes Preah Neak Pean and Ta Som. Its vast footprint and collection of carvings means that you’ll be spending some time exploring and trying to navigate your way about. It isn’t hard to visualise the almost 100,000 people that once called the area home. The East entrance has the same devas, asuras, and nagas reminiscent of the same Churning of the Ocean of Milk at Angkor Thom.
