The modern city of Mleiha is located approximately 50 km east of Sharjah. The ancient site of Mleiha comprises an extensive agricultural settlement containing numerous archaeological features dating from the post-Iron Age, Hellenistic period, and subsequent periods.

The archaeological record indicates that the earliest remains discovered at the Mleiha site date back to approximately 300 BC. However, the recent discovery of a tomb dating to the Umm Al Nar period has extended the known history of this site back to the third millennium BC.

The tomb was discovered in 1998 by a local archaeological mission affiliated with the Sharjah Archaeology Department, within a date palm plantation. It was constructed according to the architectural style characteristic of the Umm Al Nar period. The tomb consists of a circular structure with a diameter of 13.85 metres, making it the second-largest Umm Al Nar tomb discovered to date, after the Shimal Tomb, which measures 14 metres in diameter.

The tomb is built on a circular foundation of irregularly shaped stones, with an exterior façade constructed from finely dressed, regularly shaped limestone blocks. The entrance is located on the northern side and was identified by a rectangular stone bearing raised decorative motifs. The entrance leads to a passage connected to eight burial compartments or chambers, whose floors are paved with flat stone slabs.

Numerous skeletal remains and a collection of archaeological artefacts were found inside the burial chambers. These finds exhibit characteristics typical of the Umm Al Nar period and include handmade pottery, imported incised grey pottery, decorated stone vessels, bronze knives, and personal ornaments.

One particularly notable feature of this tomb is a long stone element that served as a drainage spout, allowing water accumulated on the roof to drain away.
