Buxa Fort is located at an altitude of 867 metres (2,844 ft) in the Buxa Tiger Reserve, in the Kalchini CD block in the Alipurduar subdivision of the Alipurduar district, in West Bengal, India. It is located 30 kilometres (19 mi) from Alipurduar, the nearest town. The Bhutan King used the fort to protect the portion connecting Tibet with India, via Bhutan. Still later during the unrest in the occupation of Tibet, hundreds of refugees arrived at the place and used the then abandoned fort as a place of refuge.
