The tower was designed by the Egyptian architect Naoum Shebib and completed in 1961, at 187 metres. For roughly a decade afterwards it was the tallest structure in Africa, and it remained the tallest in Egypt until well into this century.
Its shape is a lattice openwork cylinder that widens slightly towards the top, read almost universally as a lotus stalk — pharaonic ornament rendered in reinforced concrete, at a moment when the new republic was looking for a visual language that was Egyptian without being colonial.
It stands on Gezira, the long island in the Nile that was laid out as khedivial gardens in the nineteenth century and became Zamalek, the city's most cosmopolitan district. The tower sits at its southern end, on ground that was part of those gardens.
A story repeated all over Cairo says the tower was built out of money the United States offered Nasser personally, and put up as a deliberate gesture. It is a good story and it is not documented; treat it as folklore rather than history.
