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).

Year 331 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Potitus and Marcellus (or, less frequently, year 423 Ab urbe condita). The denomination 331 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
