Three Pagodas Pass
Three Pagodas Pass is a mountain pass in the Tenasserim Hills along the border between Thailand's Kanchanaburi Province and Myanmar's Tanintharyi Region, located at coordinates approximately 15°18′N 98°23′E and an elevation of 282 metres (925 ft).[1][2] The pass is named for three small white pagodas erected at the site, which serve as a landmark for the Thai-Myanmar frontier.[3] Historically, the pass functioned as a critical overland route connecting the Irrawaddy River valley in Myanmar to the Chao Phraya River plain in central Thailand, facilitating trade in goods such as teak, gems, and rice, as well as serving as the primary conduit for Burmese military invasions into Siamese territory during the Ayutthaya Kingdom period from the 14th to 18th centuries.[4][5] Armies under Burmese kings like Bayinnaung repeatedly traversed the pass to launch campaigns against Ayutthaya, exploiting its relatively low elevation and direct path despite challenging terrain that included dense jungles and rivers.[5] In modern times, it operates primarily as a local border checkpoint with a modest market trading Burmese goods like jade and textiles, though formal crossings for foreigners have been restricted since the COVID-19 pandemic, limiting its role to symbolic and minor commercial functions amid ongoing regional border tensions.[3][6]
