Turris Tamalleni
Turris Tamalleni was a town in North Africa, dating from the Carthageinian, Roman, Byzantine and Vandal era.

Geography 
The town was west of Tacapes and South of Capsa. It is located on the oasis of Mansura, 1.5 kilometers from Telmine and 7.5 kilometers from Kebili.

History
Turris Tamalleni town was founded before Carthage, when the Nybgenii Tribe established a fortified granary and a fortified residence for the tribal head. It was renamed in the 1st century  C. Civitas Nybgenorium, and remained the center of the Nybgenii Tribe and the name Turres  being probably the indigenous name. It was originally a fort on the Roman Limes,  and linked by Roman Road under Domitian. Later it became a municipium under Hadrian(about 105AD) taking the name Turris Tamalleni.  It is mentioned in the Antonine Itinerary on the road on the borders of Tripoli and Leptis Magna. During the latter Roman era it was a Bishop's seat and a center of resistance of the Almoravids. The city was taken and destroyed by the Almohads in 1205AD.
An Arab town called Torrah or telmin was built  from the rubble of the Roman town and is identified as runs at ruins of Oum-Es-Samâa.
Today, nothing remains of the ancient city.  All that remains of the ancient town is two large irrigation basins separated by a wall, which were restored in 1780 by the Bey of Tunis, they form a lake of one hectare.

Bishopric
The Bishopric founded in the fourth century ceased to function with the arrival of the Arab forces, but remains a titular see of the Roman Catholic Church. The current titular bishop is Linus Lee Seong-hyo, auxiliary bishop of Suwon.
