Angkor Wat (Angkor Archaeological Park)

This temple city is Cambodia's number one drawcard. Accessed from the town of Siem Reap, the temples of the Angkorian period are so ambitious in scale and in the majesty of their construction, that Angkor Wat is rated as one of the world's must-see ancient sites. Built between AD 802 and 1432, this was the largest city in the world during the medieval age and the vast powerhouse of the Khmer kings who endeavored to outbid their predecessors in the beauty of their construction. As the city's wooden dwellings were encroached and then decayed by the surrounding jungle, what remains today, are just those mighty temples.

The temple of Angkor Wat itself, the world's largest religious building, is only one sliver of the site in total, and the sprawling circuit of temples deserves three days to explore if you want to understand the scope of the Angkorian period's architectural achievements. For those short on time though, the main highlights after Angkor Wat are the tree-root clasped temple of Ta Prohm (which first found international fame as a location used in the movie Tomb Raider), the Bayon Temple for its 216 stone-carved faces, Angkor Thom, and Preah Khan.
