Don Chedi Monument

Don Chedi Monument in Suphan Buri marks the site where King Naresuan the Great is said to have killed the Burmese crown prince Mingyi Swa in a duel fought on elephant-back in 1593, a victory that ended Ayutthaya’s period as a Burmese vassal state. A statue of Naresuan mounted on his war elephant, mid-strike, stands beside the chedi that gives the monument its name. Entry is free and the grounds are open daily from 06:00 to 18:00.

The chedi itself isn’t the 16th-century original. By the early 1900s the memorial Naresuan is said to have built here had subsided into an unmarked mound, and it took the Governor of Suphan Buri’s rediscovery of the ruin in 1913, followed by Prince Damrong Rajanubhab’s research into the Luang Prasoet Chronicle, to identify it as the Nong Sarai battle site. King Vajiravudh made a pilgrimage to the newly identified spot in January 1914. The chedi visitors see today, completed in 1959 over the original foundations, is a 20th-century reconstruction rather than a restoration — the elephant statue, by sculptor Silpa Bhirasri, was unveiled the same year.

Step inside the chedi’s base and there’s a small multimedia room built around models of the Thai and Burmese armies, using light and sound to walk through the battle and the 1913 rediscovery. It takes ten to fifteen minutes and works well as a primer before circling the grounds outside, where mature trees give the memorial lawns real shade — useful given how exposed Suphan Buri’s flat rice-growing plains get by midday.

Insider Tip: Visit in mid-to-late January and you’ll catch the annual Don Chedi Memorial and Red Cross Fair, roughly two weeks of concerts, folk theatre, and food stalls built around an evening light-and-sound show that re-enacts the elephant duel — a separate ticketed event from the free daytime monument visit.

Watch out: Outside fair season, there’s little shade for a midday visit and no on-site food beyond a scattering of stalls, so eat before you come or plan a stop in Don Chedi town rather than counting on the grounds.

The monument sits within Suphan Buri province, and history-minded visitors can follow the battle thread to Bueng Nong Sarai Historical Site, the marsh where the wider battle that framed Naresuan’s duel is thought to have unfolded.
