Al-Akhdhar is an archaeological site in Ash Sharqiyah, Oman. It is a cemetery containing with remains dating from the Umm an-Nar, Wadi Suq, Late Iron Age (Samad), and Islamic periods.
The site is located next to the Wadi Samad. In 1973–4, Shaikh Hamdan al-Harthi, a resident of Samad al-Shan, informed the newly formed Department of Antiquities of the existence of pre-Islamic graves at this site. A British team lead by D. Brian Doe and Beatrice de Cardi surveyed the site and put it in their gazetteer. In 1974, eight of the graves were excavated, but without any documentation.
In 1980, Gerd Weisgerber began to record the finds[clarification needed] and visited the site when he could. In 1981, B. Vogt and A. Tillmann of the German Mining Museum in Bochum excavated the site. Paul Yule used some of the finds for his study of the Samad Late Iron Age. A full report was published in 2015.
This archaeological site, like most in the Sultanate is in danger of being built on or otherwise destroyed.
