The temples of Angkor are ancient, massive, stunning feats of architecture. Angkor was the capital city of the Khmer Empire from the 9th century until the 15th century and may be the largest pre-industrial city in the world. “Angkor” is actually the Khmer word for “city.” There were more than 1,000 temples that made up the Angkor complex, although now many of them are just piles of brick and rock. The ones that still stand and have been restored include Angkor Wat (the world’s largest single religious monument & Cambodia’s #1 tourist spot), Bayon, Angkor Thom, and Ta Prohm. They are now protected as a UNESCO World Heritage site.
