The Octagon

The Octagon, in Greater Cairo, will soon be the new headquarters of the Egyptian Ministry of Defense. Extending over 34 square miles (89 square kilometers) with a 50.5 million-square-foot (4.6 million-square-meter) floor plan, it is the largest defense headquarters in the world. It has eight octagon-shaped outer buildings—representing the eight branches of the Egyptian Armed Forces—and two inner ministerial buildings.
