This is the tall, thin communications tower that you'll see when heading to and from downtown on the 6th of October Bridge. The concrete sheathing on the outside of the 187m (614 ft.) edifice is said to represent the lotus flower. It took the Nasser government 5 years to build, starting in 1956, and they say it was meant to show that Egypt was capable of building the Aswan High Dam (which was ultimately only completed with Russian assistance in 1970). There is an elevator to the top, and on a clear day the view of the city is spectacular. Try going just before sunset to get the full range of light. There is also a restaurant and some toilets, neither of which I would recommend.
