Bayon, Cambodia

Built in honour of one of Cambodia’s most famous kings, Jayavarman VII, Bayon is a 12th-century state temple that’s a unique architectural feat in the heart of Angkor Thom. Fifty-four gothic towers carved with 216 gargantuan smiling faces of Avalokiteshvara – the bodhisattva of compassion – fill the temple, and the design showcases the shift from Hinduism to Mahayana Buddhism. With Angkor Wat not far away, Bayon, its off-the-beaten track little sister, is a close second in popularity.
