Al-'Uqayr
Al-Uqayr is a port on the Gulf coast east of the great oasis of al-Ahsa. It served as the maritime outlet for the oasis and for Najd farther inland, connecting caravans from the interior with ships on the Gulf. Goods could pass between the date gardens and markets of al-Ahsa and the sea through this coastal station, where warehouses and other buildings catered to the movement of commerce.
