Phanom Rung has a knock-me-dead location. Crowning the summit of a spent volcano, this sanctuary sits a good 70 storeys above the paddy fields below. To the southeast you can clearly see Cambodia’s Dongrek Mountains, and it’s in this direction that the capital of the Angkor empire once lay. The Phanom Rung temple complex is the largest and best-restored Khmer monument in Thailand. It took 17 years to complete the restoration.
