Aden (pronounced /ˈeɪdən/; Arabic: عدن ʻAdan, pronounced [ˈʕɑdæn]) is a seaport ceety in Yemen, located by the eastern approach to the Red Sea (the Gulf of Aden), some 170 kilometres east of Bab-el-Mandeb. Its population is approximately 800,000. Aden's ancient, natural harbour lies in the crater of an extinct volcano which now forms a peninsula, joined to the mainland by a low isthmus. This harbour, Front Bay, wis first uised bi the ancient Kinrick o Awsan atween the 5t an 7t centuries BC. The modern harbour is on the ither side o the peninsulae.
Aden consists o a number o distinct sub-centers: Crater, the oreeginal port ceety; Ma'alla, the modern port; Tawahi, kent as "Steamer Point" in colonial days; an the resorts o Gold Mohur. Khormaksar, locatit on the isthmus that connects Aden proper wi the mainland, includes the ceety's diplomatic missions, the main offices o Aden University, an Aden Internaitional Airport (the umwhile Breetish Air Force base RAF Khormaksar), Yemen's seicont biggest airport. On the mainland are the sub-centres o Sheikh Othman, a umwhile oasis aurie; Al-Mansura, a toun planned bi the Breetish; an Madinat ash-Sha'b (umwhilie Madinat al-Itihad), the site designatit as the caipital o the Sooth Arabian Federation an nou hame tae a lairge pouer/desalinization facility an additional faculties o Aden University.
Aden encloses the eastren side o a vast, natural harbor that comprises the modern port. The volcanic peninsula o Little Aden forms a near-mirror image, enclosin the harbor an port on the wastren side. Little Aden became the site o the oil refinery an tanker port. Baith wur established an operatit bi British Petroleum till they wur turned ower tae Yemeni government awnership an control in 1977.
