One of Abu Dhabi's westernmost islands, located north of Ras Ghumays. The island was visited by members of ADIAS between 1993 and 1995, at which time some 20 archaeological sites were identified. These range in time from a site (Site J) with stone tools belonging to the Arabian bifacial tradition; to a site (Site K) with 'red-ridged ware', probably originating on Bahrain, which is datable to c. 2000-1700 BC; to several sites showing late pre-Islamic pottery dating to the first-fourth centuries AD and comparable to material al-Dur and Mileiha; and finally to sites showing occupation during the the last few centuries, with both local and Chinese pottery comparable to that found at Julfar in the northern Emirates. It is likely that in some periods the human occupation of Ghagha' was only seasonal.
