The discovery came as a result of archaeological excavations conducted by the Department of Archaeology at the College of Arts and Social Sciences in Sultan Qaboos University from 2013 to 2017.
Dahwa is located 24km west of the wilayat of Saham on the edge of the Al Hajar Mountain ranges. The faculty members, technical staff and graduate students in the department participated in the excavation and archaeological surveys.
The site dates back to the civilisation of Umm al Nar, which dates from 2500 to 2000 BC. It is the oldest settlement to date discovered in the north of the Batinah plain. What distinguishes the site is the initial indications of its external relations with Sindh, in which the pottery or the storage jar, which was manufactured in the civilisation of Harappa, then in Sindh.
It is believed that the place of manufacture of the pottery found in Dahwa is located in the central region of the Sindh valley in Pakistan, specifically the Mohenjo Daro region, where archaeologists found the largest city in the world dating back to the early Bronze Age (2500-2000 BC).
Archaeologists also believe that these pottery were used to transport some products from the Indus Valley by small boats across the Indus River to the shores of the Arabian Sea. They were transported by larger boats to a port near the wilayat of Saham and then were carried on shoulders for 24km inwards through the edges of the Al Hajar Mountains to the Dahwa area.
The strong presence of Sindh pottery in Dahwa indicates the extent of trade activity that prevailed between Oman and Sindh during the early Bronze Age. The nature of the materials that were imported from Sindh and transported in these jars has not yet been identified. Oman was famous for the export of copper to Sindh, Mesopotamia and Iran during the period of Umm al Nar culture.
