Historians believe that the original building was built from wood, rather than stone, because it was not meant for religious observation. See the Royal Enclosure while visiting the rest of Angkor Thom, a 2,470-acre (1,000-hectares) area that includes the Bayon temple, which sports large, enigmatic faces; the beautifully carved Terrace of the Elephants and Terrace of the Leper King; and Baphuon, an 11th-century “temple mountain.”
Admission to Angkor Thom (and the Royal Enclosure), is included in an Angkor Pass, which is available in 1-day, 3-day, and 7-day versions (multi-day passes don’t have to be used on consecutive days).
