Victoria Dam, Adikarigama, Sri Lanka.

The massive Victoria Dam, built in the form of an 'egg-shell' - double convex shape, on British aid, holds back the waters of the Mahaweli Ganga at Adikarigama, Sri Lanka. The dammed up water runs through a tunnel and powers turbines to generate electricity for the national grid. Completed in the 1980s it has already paid back all the loans taken to build the dam.
