King U Thong founded this temple in 1357 to house monks returning from ordination in Sri Lanka and in 1592 King Naresuan built its fantastic bell-shaped chedi after a victory over the Burmese. The landscaped gardens make this one of Ayuthaya's most photogenic ruins. There's a 7m-long reclining Buddha near the entrance and the local belief is that If you can get a coin to stick to the Buddha's feet, good luck will come your way.
