Medal - Singburi Province

(en) The provincial seal presents the history of Khai Bang Rachan. When the Burmese attacked Ayutthaya in 1765, 11 leaders with villagers from Bang Rachan fought the army when it stopped north of Ayutthaya. They managed to delay them for five months before they were finally defeated, soon thereafter Ayutthaya fell as well. Annually on 4 February a ceremony is held in remembrance of these local heroes. This story was also made into a movie in Thailand.

The Bang Rachan Camp is a place of great historical importance. This land recorded the events of bravery and sacrifice made by the Thai heroes on the third lunar month of the year of the Rooster in 1765. The villagers of Ban Bang Rachan united to fight against the tremendous Burmese army and could endure eight Burmese attacks for five months before being conquered on Monday, the second day of the waning moon in the eighth lunar month in 1766. This is considered an important monument. The present Bang Rachan Camp is an imitation of the ancient camp. Within the Khai Bang Rachan Park, lies the Heroes of Khai Bang Rachan Historical Centre which has three exhibition rooms.
