Dammam is the 5th largest city of Saudi Arabia
and it is the 216th largest city of the World.

Dammam is the capital of Eastern Province, Saudi Arabia.
The judicial and administrative bodies of the province
and several government departments are located in the city.

Dammam is the largest city in the Eastern Province,
and the fifth largest in Saudi Arabia,
after Riyadh, Jeddah, Mecca and Medina.

The origins of the name "dammam" are disputed.
Some say that it is onomatopoeic
and was given to the area because of a drum positioned
in a nearby keep,
which was sounded to alert the residents of returning fishermen's ships. others say that the name comes from the arabic word "dawwama" (whirlpool),
which indicated a nearby sea site that dhows usually had to avoid.

Dammam was first inhabited by a family from Al Bin Ali clan and a number of Persian Howela families in early 1923.
