In the eastern desert close to the Iraqi border, the Azraq Oasis was a traditional caravan stopping point. The most striking remain is the gloomy black-basalt Roman fortress, later used by T.E.Lawrence as a headquarter during the Arab Revolt.

The oasis is an important stopping point by air as well as land. Each year flocks of birds visit Azraq during their annual migration, making this a must-see for any bird enthusiast.
