The name "Al-Dawadmi" is believed to be derived from the abundance of a particular type of tree known locally as al-dawadim. This tree is known for its use in tanning processes. The name may have originated from the region's notable presence of samar and acacia trees, which produce a reddish substance reminiscent of blood. These trees are plentiful in the area, giving rise to the name associated with their abundance and the significance of their products.

Dawadmi town holds historical significance as one of the ancient human settlements located in the heart of the Arabian Peninsula. The mountains and valleys of the region are adorned with traces of human presence, including inscriptions, graffiti, and depictions of both humans and animals. Notably, faded images of large lions can be found, surrounded by remnants of mining operations and scattered stone rubble. These archaeological remnants provide evidence of the rich history and early human activity in the area.

The governorates of the Riyadh region are distinguished by a diverse cultural heritage, formed by the successive civilizations that this region experienced that left behind various archaeological monuments.

Survey studies conducted by the Heritage Authority of the Ministry of Culture revealed the presence of more than 35 important archaeological sites in the Dawadmi Governorate, some of which contain animal inscriptions, drawings and historical writings dating back to the Paleolithic, Middle and Modern Stone Ages, the most important of which are two historical inscriptions written in the Sabaean script in “Masil al-Jamh Mountains.” The first inscription dates back to King “Abu Karib As’ad,” one of the most famous kings of Himyar, in the first third of the fifth century AD, and the second inscription dates back to the year 516 AD to King Ma’ad Yakrib al-Himyari. Both inscriptions indicate the presence of military campaigns launched against some tribes of Central Arabia.

Aside from these two inscriptions, there are inscriptions and drawings on large rocks of ibex and ostriches on the facades of the mountains in Dawadmi, in addition to inscriptions, rock drawings, and Islamic writings in the sites of “Qubi’a” and “Safqa,” and rock drawings of human and animal forms on the “Thalan Mountains” series, the most notable of which is the site. “Matiwi Dalaa” on the southwestern side.
