ADEN:
Aden is one of the most beautiful coastal cities in Yemen, known for its wonderful beaches, old buildings, impregnable castles and many souks. It is, also, the economic capital of Yemen, 170 kilometers east of Bab-el-Mandeb. 
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, was first used by the ancient Kingdom of Awsan between the 5th and 7th centuries BC. The modern harbour is on the other side of the peninsula.
