Asia’s oldest refinery and the birthplace of crude oil “Digboi”
When railway tracks were being laid during the 18th century, oil traces were found in Digboi, which led to the first oil well being dug in the city. Because of this, Digboi is also known as the oil city of Assam. Digboi has the oldest oil well in operation. Apart from oil, Digboi is also famous for the Saikhowa Wildlife Sanctuary, the Golf Course, and its War Cemetry.
