Construction
At the direction of Alexander the Great, the Macedonian architect Deinokrates lays out the new city of Alexandria on the Nile delta in Egypt. Its central north-south and eastwest streets are each 14 m (46 ft) wide, dividing the city into four quarters, each with its own character. The plan is completed later by Ptolemy I, who joins several rocky islands and builds a long
causeway to form two harbors set off by the famous Lighthouse of Pharos (named after the island on which it is built).
