The slogan of Alexandria University Contains the Lighthouse of Alexandria which is a huge building on the island of Pharos at the entrance of the eastern port of Alexandria, constructed in the era of Ptolemy II at about 280 BC. It consists of four floors: the first is squared, the second is octagonal and the third is rounded and contains a large lamp that lies on the top of three pillars with the highest in the form of the statue of the God of the Sea "Poseidon". The Lighthouse length is about 120 meters high and built of limestone and its columns are made of granite and decorated with marble and bronze.
