The Stunning Temples of Angkor Wat and Thom

Located in a part of Cambodia that was once the seat of the famous Khmer Empire, Angkor (meaning 'capital city' in Khmer) was the heart of this civilization that thrived from the 9th to 15th centuries CE. There are over one thousand different temples in Angkor of different sizes and scales, all of which have been restored as a landmark of historic Khmer architecture. The entire site is preserved as a UNESCO World Heritage Site, but even if you can't make the journey to Cambodia, here is a tour of Angkor's highlights.

In 2007, a group of researchers concluded the Angkor had been the largest preindustrial city in the world, with an elaborate infrastructure system that connected at least 1,000 square kilometers (390 square miles) to the temples at its center. It is estimated that the Angkor area may have supported up to one million people.
