Bidaa Bint Saud

Bidaa Bint Saud ( ar, بِـدَع بِـنْـت سـعـوْد, Bidaʿ Bint Saud) is an archaeological site in Al-Ain Region, Abu Dhabi, United Arab Emirates, notable for its Hafit Period tombs, Iron Age irrigation systems and rare remains of an Iron Age building thought to have been a distribution centre for water from two ''aflaj'' (systems of underground and surface waterways). It is a listed UN World Heritage Site. Finds from the site are displayed at Al Ain National Museum.

The dating of pottery from the ''aflaj'' (singular falaj) waterways found at the site demonstrates a south-eastern Arabian origin for this distinctive system of irrigation, previously thought by many scholars to have been Persian in origin. The dating of ''aflaj'' in Bidaa bint Saud, Al Ain and Buraimi, both of which are in the historical region of Tawam, has been placed several centuries prior to the Achaemenid Empire, which had previously been credited with the innovation.

The site, located some north of Al Ain, is thought to have been a stopping place on a long-established caravan route from settlements at Al Ain to the Northern Emirates. The rocky outcrop of Garn bin Saud looms some above the site and is dotted with burial remains.

Bronze Age tombs

A number of distinctive Hafit Period (3200 to 2600 BCE) tombs litter the eastern face of Garn bint Saud, similar to those found at sites such as Jebel Hafit, Jebel Buhais and Buraimi. These have collapsed and would originally have had domed roofs. It is likely the location of the Hafit remains, the Hafit people being nomadic and pastoral, is because of a source of groundwater, a pattern supported by other Hafit era inland finds, including those at Jebel Hafit and Jebel Buhais.

Iron Age waterways

A second set of collective graves found at the site dated from the Iron Age and were also built of uncut or rough-cut stone and formed into a variety of shapes. These were divided into several chambers, each of which contained the remains of several people. Despite having been plundered in the past, excavations from these Iron Age tombs yielded a number of artefacts, including pottery and stone vessels, dagger blades, bronze arrowheads, and beads.

It is thought Bidaa Bint Saud became an important site during the Iron Age, both as a caravan stop and as a settled community of farmers that used the ''falaj'' irrigation system.

Two of these irrigation passages have been partly excavated at Bidaa bin Saud, with a number of sections remaining in reasonable condition. In one of the excavations, a number of sandstone-lined shaft holes were discovered, as well as a stepped underground access point and a large open cistern. Evidence of formerly irrigated land has also been found at the site.

The mother well is thought to have been relatively shallow, about away from the head of the ''falaj'' systems.

Located some from the main access point of the ''falaj'', archaeologists have also excavated a large mud-brick building containing a hall of . Parts of the remains stand up to high and, while the roof is missing, there is evidence it was supported by 12 columns. Storage rooms were a later addition and contained finds of many storage jars. While the building's precise purpose remains unclear, archaeologists think it was likely a distribution point for the water from the ''falaj'' systems and it has been dubbed ''Bait Al-Falaj'' ( ar, بَـيْـت الْـفَـلَـج, lit=House of The Falaj).
