| This monument, resembling an Egyptian pyramid, marks the most remote southern origin of the Nile in Burundi, in east-central Africa. From the Ruvyironza River, the Nile’s southernmost headstream in Burundi, the great river is 6,695 km (4,160 mi) long. To the northeast of the Ruvyironza is Lake Victoria, the Nile’s main source. |
