Egypt Unveils 'Octagon,' World's Largest Defense Headquarters

Egypt has revealed its new Ministry of Defense headquarters, named the 'Octagon,' which is described as the largest defense complex in the world. The facility is nearly eight times larger than the United States Pentagon. The complex features eight external octagonal buildings, each representing a branch of Egypt's armed forces, along with two central buildings. Unlike the Pentagon's five-sided design, Egypt opted for an eight-sided structure to symbolize its military branches.
