Sir Arthur Cotton Museum is a unique civil engineering museum in Rajahmundry which was set up in 1988 in honour of the eponymous Sir Arthur Cotton. A British irrigation engineer and a general in colonial India, he was responsible for directing the establishment of an efficient system of irrigation in the Godavari districts. Known as ‘Cotton Dora’ and ‘Delta Architect’, his contribution in the construction of dams and canals like the Dowleswaram barrage, Prakash barrage and the Kurnool Cuddappah Canal helped make the river Godavari, a reliable water resource. The museum relays how his skills and efforts transformed the area. Located in the building which was formerly managed by the Executive Engineer of the Godavari Head Works division, the museum is also in close proximity to the Dowleswaram barrage itself where museum-goers can witness the functioning of one of Cotton’s designs as well.
