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.
