After remaining under threat for many decades, Iraq's famous marshes have finally been added to UNESCO 's World Heritage Sites list.

Drained time and again since the 1950s and then later in the 1990s under the rule of Saddam Hussein, the wetland areas in Southern Iraq have no doubt stood the test of time.

Here are 6 things you should definitely know about this amazing wetland:

1. Marsh Arabs are the primary inhabitants of the wetland area

The Marsh Arabs are descendants of ancient Sumerians, with a civilization dating back 5,000 years. Living in secluded villages of reed houses throughout the marshes, the number of Marsh Arabs has decreased since the 1950s, when there was an estimated 500,000. During Hussein's reprisal, 80,000 to 120,000 fled to Iran.
