Kanchanaburi Province, located in western Thailand near the Myanmar border, has a deep history stretching back to prehistoric times. Archaeological finds, including ancient stone tools, pottery, and cave paintings, indicate early human settlements. Kanchanaburi's strategic location made it a significant military outpost from the Ayutthaya period, serving as a frontline defense against Burmese invasions. The well-known Three Pagodas Pass was a vital route for military campaigns. During the Thonburi period, this area saw conflict in ten wars with Burma, and in the early Rattanakosin era, the famous Nine Armies War took place at Lad Ya Plain.
In 1831, King Rama III fortified Kanchanaburi by constructing city walls and defensive strongholds, establishing a stable frontier for the kingdom. Originally based in Lad Ya, the provincial seat was moved to Pak Phraek in 1831, where it remained until 1955 before relocating to Ban Bo.
