The National Museum added the tripartite stone to its museum display.

Triliths are enigmatic 2,000-year-old stone monuments found throughout the coastal highlands of Southern Arabia, from ?a?hramawt in Yemen to Ra?s al-??dd in Oman. They consist of three upright flat stones forming a triangular pyramid and are often arranged in rows alongside dry watercourses and possible ancient trade routes. Triliths are also associated with large round firepits, and have been dated (from the charcoal in these firepits) to the Late Iron Age (200 BCE–400 CE). They mark special spaces of particular meaning for rituals we still do not understand, and interpretation is challenging as no human remains or other artefacts have been found under or around the stones. The small trilith group exhibited here was relocated in December 2018 from W?d? ?ayy in Duqm by the Italian-Czech archaeological expedition.

Triliths are mysterious 2,000-year-old stone monuments distributed throughout the costal landscape of Southern Arabia from Hadhramawt in the Republic of Yemen to R’as al-Hadd in the Sultanate of Oman. They consist of three flat upright stone, angled inward to form a pyramid, and are often arranged in rows alongside dry watercourses, Triliths are also associated with large round fireplaces and have been dated (from the charcoal in the fireplaces) to the Late Iron Age (200 BCE-400CE).

Although they appear to mark places of special meaning for ancient rituals, further interpretation is challenging as no human remains or other artefacts have been found under trilith monuments.

The small trilith group exhibited here weighs nearly 900 kilograms. It was endangered by dam construction works in Wadi Sayy, near Duqm, and consequently relocated to the National Museum. Rescue and relocation operations were carried out by a team of archaeologists from the Italian and Czech Republics expeditions under the auspices of the TSMO (Triliths: Stone Monuments of Oman) Expedition in Arabi al-Awwal 1440 AH/ December 2018 CE.

Trilith relocation to the National Museum was funded by Roman Garba.
