East Mebon is a large temple-mountain-like ruin, rising three
levels and crowned by five towers. Jayavarman IV, a usurper
to the throne, moved the capital from Angkor to Koh Ker in 928
AD. Sixteen years later Rajendravarman II returned the capital
to Angkor and shortly thereafter constructed East Mebon on an
island in the middle of the now dry Eastern Baray. The temple
was dedicated to Shiva in honour of the King's parents.
