The first half of the 12th century was dominated by one of the principal kings of Cambodia, - Suryavarman I. The capital became established in the centre of Angkor Thom with various monuments surrounding a royal palace. This period represents the height of the artistic culture. Monuments include the Baphuon, Angkor Wat and Banteay Samre. The Western Baray, another vast reservoir, was also excavated.
