TEHRAN –A historical Ab-Anbar (cistern) in Sari, northern province of Mazandaran, has reopened for visitors and history buffs, Sari’s tourism chief has announced.

The historical structure is planned to be promoted as one of the region’s tourist destinations as its restoration project has recently come to an end, Mohsen Bastani said on Monday.

The term Ab-Anbar is common throughout Iran as a designation for roofed underground water cisterns. It associates with water management systems in arid areas that are reliant on permanent springs or on seasonal rainwater.

Such underground reservoirs or Ab-Anbars are parts of the iconic qanat systems, which rely on snow-fed streams flowing down from surrounding mountains.

Qanats, according to UNESCO, provide exceptional testimony to cultural traditions and civilizations in desert areas with an arid climate.

Sandwiched between the towering Alborz mountain range and the Caspian Sea, Mazandaran has a rich yet turbulent history. An early civilization flourished at the beginning of the first millennium BC in Mazandaran (Tabarestan).

Its insecure eastern and southeastern borders were crossed by Mongol invaders in the 13th and 14th centuries. Cossacks attacked the region in 1668 but were repulsed. It was ceded to the Russian Empire by a treaty in 1723, but the Russians were never secure in their occupation. The area was restored to Iran under the Qajar dynasty.

The northern section of the region consists of lowland alongside the Caspian and upland along the northern slopes of the Alborz Mountains. Marshy backlands dominate the coastal plain, and extensive gravel fans fringe the mountains. The climate is permanently subtropical and humid, with very hot summers.
