Mersa Matruh (Arabic: مرسى مطروح, romanized: Marsā Maṭrūḥ, IPA: [ˈmæɾsæ mɑtˤˈɾuːħ]), also transliterated as Marsa Matruh, is a port in Egypt and the capital of Matrouh Governorate. It is located 240 km (150 mi) west of Alexandria and 222 km (138 mi) east of Sallum on the main highway from the Nile Delta to the Libyan border. The city is also accessible from the south via another highway running through the Western Desert towards Siwa Oasis and Bahariya Oasis.

In ancient Egypt and during the reign of Alexander the Great, the city was known as Amunia. In the Ptolemaic Kingdom and later during the Byzantine Empire, it was known as Paraitónion (Koinē Greek: Παραιτόνιον). During the Roman Empire, it was called Paraetonium in Latin, which became al-Bāritūn (Arabic: البارتون) after the mid-7th century Muslim conquest of Egypt.^[1] As a British military base during World War II, several battles were fought around its environs as the German Afrika Korps attempted to capture the port. It fell to the Germans during the Battle of Mersa Matruh, but was recaptured following the Second Battle of El Alamein.

Mersa Matruh is served by Mersa Matruh International Airport. The city features soft white sand beaches and calm transparent waters; the bay is protected from the high seas by a series of rocks forming a natural breakwater, with a small opening to allow access for light vessels.

Alexandria (/ˌælɪɡˈzændriə/ or /-ˈzɑːnd-/;^[6] Arabic: ٱلْإِسْكَنْدَرِيَّةُ al-ʾIskandarīyah;^[7] Ancient Greek: Αλεξάνδρεια, romanized: Alexándria)^[8][9] is a Mediterranean port city in Egypt. Founded in c. 331 BC by Alexander the Great,^[10] Alexandria grew rapidly and became a major centre of Hellenic civilisation, eventually replacing Memphis, in present-day Greater Cairo, as Egypt's capital. During the Hellenistic period, it was home to the Lighthouse of Alexandria that ranked among the Seven Wonders of the Ancient World, as well as the storied Library of Alexandria. Today, the library is reincarnated in the disc-shaped, ultramodern Bibliotheca Alexandrina. Its 15th-century seafront Qaitbay Citadel is now a museum. Called the "Bride of the Mediterranean" by locals,^[11] 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, the ninth-largest urban area in Africa, and the 79th-largest urban area by population on Earth.

The city was founded originally in the vicinity of an Egyptian settlement named Rhacotis (that became the Egyptian quarter of the city). It retained this status for almost a millennium, through the period of Roman and Eastern Roman rule until the Muslim conquest of Egypt in 641 AD, when a new capital was founded at Fustat (later absorbed into Cairo).

Alexandria was best known for the Lighthouse of Alexandria (Pharos), one of the Seven Wonders of the Ancient World; its Great Library, the largest in the ancient world; and the Necropolis, one of the Seven Wonders of the Middle Ages. Alexandria was the intellectual and cultural centre of the ancient Mediterranean for much of the Hellenistic age and late antiquity.^[10] It was at one time the largest city in the ancient world before being eventually overtaken by Rome. The city has Greco-Roman landmarks, old-world cafes, and sandy beaches.

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.^[12] 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.
