Carvings show that everyday Angkorian buildings were wooden structures not much different from those found in Cambodia today. The impressive stone buildings were not used as residences by members of the royal family. Rather, they were the focus of Hindu or Buddhist beliefs that celebrated the divinity, or buddhahood, of the monarch and his family. Coedès suggests that they had the dual function of both temple and tomb. Typically, their dimensions reflected the structure of the Hindu mythological universe. For example, five towers at the centre of the Angkor Wat complex represent the peaks of Mount Meru, the centre of the universe; an outer wall represents the mountains that ring the world's edge; and a moat depicts the cosmic ocean. Like many other ancient edifices, the monuments of the Angkorian region absorbed vast reserves of resources and human labour and their purpose remains shrouded in mystery.
