The site of Mowaihat is located on the oustkirts of Ajman. In 1986,
while laying a new sewage pipe, workers from the Municipality discovered
a circular Umm al-Nar-type tomb, c. 8.25 m in diameter. A rescue excavation
was conducted which recovered numerous examples of soft-stone
and painted Umm al-Nar ceramic vessels, as well as over 3000 beads,
two stamp seals, a number of copper
implements, and the skeletal remains of several dozen individuals.
At the time of its discovery, the Mowaihat tomb represented the first
indication of Umm al-Nar period occupation in the Northern Emirates.
Subsequent work has now identified major sites of this period on the
Gulf coast at al-Sufouh, Tell Abraq and Shimal. The material from Mowaihat forms the bulk of the archaeological finds on display in the Ajman Museum.
