TEHRAN—A restoration work has come to an end on a Qajar-era (1789-1925) Ab-Anbar (cistern), which is located in the city of Bafq, the central province of Yazd, Bafq’s tourism chief has said.

The project involved strengthening the mud-brick structure, repairing stairs and rooftops, and replacing worn-out materials, Leili Ranjbar said on Monday.

The historical monument is one of the biggest cisterns in the region, which is located in the historical texture of the city, she noted.

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 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.

In July 2017, the historical structure of the city of Yazd was named a UNESCO World Heritage. Wedged between the northern Dasht-e Kavir and the southern Dasht-e Lut on a flat plain, the oasis city enjoys a very harmonious public-religious architecture that dates from different eras.

Yazd is usually referred to as a delightful place to stay, or a “don't miss” destination by almost all of its visitors. The city is full of mud-brick houses that are equipped with innovative badgirs (wind catchers), atmospheric alleyways, and many Islamic and Iranian monuments that shape its eye-catching city landscape.

It is a living testimony to the intelligent use of limited available resources in the desert for survival. Water is brought to the city by the qanat system. Each district of the city is built on a qanat and has a communal center.

The use of earth in buildings includes walls and roofs through the construction of vaults and domes. Houses are built with courtyards below ground level, serving underground areas. Wind catchers, courtyards, and thick earthen walls create a pleasant microclimate.

Partially covered alleyways, together with streets, public squares, and courtyards, contribute to a pleasant urban quality. The city escaped the modernization trends that destroyed many traditional earthen cities.

It survives today with its traditional districts, the qanat system, traditional houses, bazaars, hammams, water cisterns, mosques, synagogues, Zoroastrian temples, and the historic garden of Dolat-Abad. The city enjoys the peaceful coexistence of three religions: Islam, Judaism, and Zoroastrianism.
