Believed to have been constructed as a temple and mausoleum for King Suryavarman II at the peak of the Khmer empire in the first half of the 12th century, Angkor Wat is probably the best-preserved of the Angkorean temples. As with other Angkorean temples and walled cities such as Angkor Thom, the central theme of Khmer architecture revolved around the idea of the temple-mountain. By the time building on Angkor Wat was begun early in the 12th century, this had been elaborated to a central tower surrounded by four smaller towers. The central monument represents the mythical Mount Meru, the holy mountain at the centre of the universe, which was home to the Hindu god Vishnu. The five towers symbolise Mount Meru’s five peaks.
