Don Chedi Monument

The Don Chedi Monument (Thai: พระบรมราชานุสรณ์ดอนเดจีย์, RTGS: Phra Boromma Rachanuson Don Chedi) is a royal memorial Don Chedi district , Suphan Buri province, Thailand, built to commemorate King Naresuan of Ayutthaya's legendary 1593 victorious elephant duel over the Burmese uparaja Mingyi Swa in the battle of Nong Sarai.

It was built on the site of a ruined chedi (stupa), believed to have originally been erected by Naresuan, and comprises a new chedi covering the ruins, and a statue of Naresuan mounted on his war elephant.

The ruins were discovered by the Governor of Suphan Buri in 1913, and King Vajiravudh made a pilgrimage to the site in January 1914.

Plans were made to build a new chedi to house the ruins, but this was shelved due to the poor economy.

The debate gained national attention around 1972–1973, but was shut down as the country slid back into dictatorship following the 6 October 1976 massacre.
