Agrabit Reservoir: In the 9th century, the area of Kairouan was severely water-scarce. At that time, the drought and rain were less and the area was below sea level, making it extremely difficult to use water. The locals built 15 reservoirs to solve the problem of drinking water. The mark left by the Agrabit dynasty is now only two for visitors to visit. Standing on the high platform of specialization, the wisdom of the Kailuan people is unobstructed.
