The legacy of Chatham Saw Mill stated in 1789, with the arrival of Lt. Archibald Blair in Port Blair in his vessel Viper to establish a British settlement here. The ''Viper'' crashed near a small Island, which is now named after it as Viper Island and late he set his foot on Chatham Island. Chatham Island lies in close proximity to Viper Island. He began the survey from Chatham Island with an aim of establishing the British footholds on the islands. Thus Port Blair was used as a safe place to deport the hard-core convicts. Later, a 100 meter long bridge was constructed out of timber from Port Blair to Chatham. This historic bridge was later renovated to a modern bridge as existing today using concrete. The Chatham Saw Mill, which was established in 1883 with the second hand imported machines, met the local requirement of timber for construction works. The saw mill had witnessed to the rise and fall of several regimes in the Islands since 1883. Since then, it was the center that provided timber for the Islanders for various construction needs. During the West colonial period Chatham, British used this mill to convert huge quantity of timber for catering the various needs of London, New York and various other cities.
