King Rajendravarman, Yasovarman's nephew, returned to the region in 944. He "restored the holy city that had long remained empty", building the temples of the Eastern Mebon and Pre Rup. He also excavated the Eastern Baray, a vast reservoir of some 8 by 2 kilometres. During his reign the temples of Banteay Srei, Ta Keo and the Kleang were also built, with probably the first of the Royal Palaces located in what was later to develop into Angkor Thom.
