Mersa Matruh is a Mediterranean seaport and the capital of the Matrouh Governorate in Egypt. It is 240 km (150 mi) west of Alexandria and 222 km from Sallum, on the main highway from the Nile Delta to the Libyan border. Another highway leads south from the town, toward the Western Desert and the oases of Siwa and Bahariya.
During Ancient Egyptian times and during the reign of Alexander The Great, the city was known as Amunia. In Ptolemaic and Byzantine times it was known as Paraitonion (Παραιτόνιον), and in Roman times, as Paraetonium.
Mersa Matruh is a major Egyptian tourist resort and serves as a getaway resort for Europeans as well as Cairenes eager to flee the capital in the sweltering summer months. It is served by Mersa Matruh Airport. The city is known for its white soft sands 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.
