The Royal Library of Alexandria in Alexandria, Egypt, was once the largest library in the world. It is generally thought to have been founded at the beginning of the 3rd century BC, during the reign of Ptolemy II of Egypt. It was likely created after his father had built what would become the first part of the Library complex, the temple of the Muses — the Museion, Greek Μουσείον (from which the modern English word museum is derived).
Alexandria
Alexandria with a population of 4.1 million, is the second-largest city in Egypt, and is the country's largest seaport, serving about 80% of Egypt's imports and exports. Alexandria is also an important tourist resort. Alexandria extends about 32 km (20 mi) along the coast of the Mediterranean Sea in north-central Egypt. It is home to the Bibliotheca Alexandrina (the new Library), and is an important industrial center because of its natural gas and oil pipelines from Suez, another city in Egypt. Alexandria was also an important trading post between Europe and Asia, because it profited from the easy overland connection between the Mediterranean Sea and the Red Sea.
