Alexandria is the second largest city and a major economic centre in Egypt, extending about 32 km (20 mi) along the coast of the Mediterranean Sea in the north central part of the country. It is Egypt's largest seaport, serving approximately 80% of Egypt's imports and exports. It is an important industrial center because of its natural gas and oil pipelines from Suez. The city is also an important tourist destination and is worth a visit for its many cultural attractions and still-palpable glimpses of its past.
