opulation. Cairo is associated with ancient Egypt, as the Giza pyramid complex and the ancient city of Memphis are located in its geographical area. Located near the Nile Delta, Cairo was developed in 969 AD during the Fatimid dynasty, but the land composing the present-day city was the site of Ancient National Capitals whose remnants remain visible in parts of Old Cairo. Cairo has long been a center of the region's political and cultural life, and is titled "the city of a thousand minarets" for its preponderance of Islamic architecture. Cairo's historic center was awarded World Heritage Site-status in 1979.
