Alexandria is the second largest city in Egypt, and the largest city on the Mediterranean coast. Founded in c. 331 BC by Alexander the Great, Alexandria grew rapidly and became a major centre of Hellenic civilisation, eventually replacing Memphis, in present-day Greater Cairo, as Egypt's capital. Called the "Bride of the Mediterranean" by locals, Alexandria is a popular tourist destination and an important industrial centre due to its natural gas and oil pipelines from Suez. The city extends about 40 km (25 mi) along the northern coast of Egypt, and is the largest city on the Mediterranean, the second-largest in Egypt (after Cairo), the fourth-largest city in the Arab world, the ninth-largest city in Africa, and the ninth-largest urban area in Africa.
The city was a major centre of early Christianity and was the centre of the Patriarchate of Alexandria, which was one of the major centres of Christianity in the Eastern Roman Empire. In the modern world, the Coptic Orthodox Church and the Greek Orthodox Church of Alexandria both lay claim to this ancient heritage. By 641, the city had already been largely plundered and lost its significance before re-emerging in the modern era. From the late 18th century, Alexandria became a major centre of the international shipping industry and one of the most important trading centres in the world, both because it profited from the easy overland connection between the Mediterranean and Red Seas and the lucrative trade in Egyptian cotton.
