This impressive off-island temple on the southwest side of the city is too far to walk from the other main sights, but accessible by bike (bring water!). It is a well-preserved example of Khmer architecture in the Ayutthaya period, and it looks a lot like Cambodia’s Angkor Wat. You can climb to the steep steps of the central prang for superb views of the surrounding countryside. Its intact structure offers visitors a good sense of what a working temple might have looked like some 300 years ago.
