The world-famous High Dam was an engineering miracle when it was built in the 1960s. Today it provides irrigation and electricity for the whole of Egypt and, together with the old Aswan Dam, 6km downriver, wonderful views for visitors. From the top of the two mile-long High Dam you can gaze across Lake Nasser, the huge reservoir created when it was built to Kalabsha temple in the south and the huge power station to the north.
