An āb anbār (Persian: آب انبار) is a traditional reservoir or cistern of drinking water in Persian antiquity. The Persian phrase literally translates as "water reservoir".
To withstand the pressure the water exerts on the containers of the storage tank, the storage itself was built below ground level. One important aspect to consider here is their resistance to earthquakes. Many cities in Iran lie in a region that have been struck with massive earthquakes. However, since almost all ab anbars are subterranean structures capped barely above ground level, they inherently possess stable structures.
The construction material used for ab anbars were very tough and extensively used a special mortar called sarooj made of sand, clay, egg whites, lime, goat hair, and ash in specific proportions, depending on location and climate of the city. This mixture was thought to be completely water impenetrable. The walls of the storage were often 2 meters thick, and special bricks had to be used. These bricks were especially baked for ab anbars and were called Ajor Ab anbari. Some ab anbars were so big that they would be built underneath caravanserais such as the ab anbar of Haj Agha Ali in Kerman. Sometimes they would also be built under mosques, such as the ab anbar of Vazir near Isfahan.
Anbar can refer to :
Anbar (Arabic: الأنبار) was a town in Iraq, at lat. 33 deg. 22' N., long. 43 deg. 49' E, on the east bank of the Euphrates, just south of the Nahr 'Isa, or Sakhlawieh canal, the northernmost of the canals connecting that river with the Tigris.
Anbar was originally called Pērōz-Šāpūr or Pērōz-Šābuhr (from Middle Persian: 𐭯𐭥𐭩𐭥𐭦𐭱𐭧𐭯𐭥𐭧𐭥𐭩, meaning "Victorious Shapur"; in Parthian: 𐭐𐭓𐭂𐭅𐭆𐭔𐭇𐭐𐭅𐭇𐭓 prgwzšhypwhr; in Aramaic: פירוז שבור), and became known as Perisapora or Pirisabora to the Greeks and Romans. The city was founded ca. 350 by the Sassanid Persian king Shapur II, and located in the Sassanid province of Asōristān. Perisapora was sacked and burned by Emperor Julian in April 363, during his invasion of the Sassanid Empire. The town became a refuge for the Arab, Christian and Jewish colonies of that region. According to medieval Arabic sources, most of the inhabitants of the town migrated north to find the city of Hdatta south of Mosul.
Anbar was adjacent or identical to the Babylonian Jewish center of Nehardea (Aramaic: נהרדעא), and lies a short distance from the present-day town of Fallujah, formerly the Babylonian Jewish center of Pumbeditha (Aramaic: פומבדיתא).
