Namoratunga, Archaeological site near Kalokol, Turkana County, Kenya.

Namoratunga is an archaeological site near Kalokol in Turkana County, northern Kenya, containing 19 basalt pillars arranged in a circular formation. The columns are visible from the road between Lodwar and Kalokol and show careful placement and alignment.

The site dates to the Pastoral Neolithic; a radiocarbon sample from recent excavations gave 2398 +/- 44 BC, older than the roughly 300 BC date once assumed. Mark Lynch and L.H. Robbins described it in 1978 and proposed it as an archaeoastronomical site. It was submitted to UNESCO's Tentative List on 30 June 2023.

Namoratunga means "people of stone" in the Turkana language, a name shared with Namoratunga I at Lokori, a cairn burial site without pillars. The 19 basalt pillars stand inside a circular stone formation, and the site is registered as GcJh3. It was submitted to UNESCO's Tentative List on 30 June 2023.

The dry season from June to October offers the best conditions for visiting, when the roads are easier to travel and weather remains more stable. Access through Kalokol town is possible, but ask locals for exact directions and current conditions before heading out.

The star-alignment idea comes from Mark Lynch and L.H. Robbins, who described the site in 1978 and linked the pillars to seven star systems, among them Triangulum, the Pleiades and Sirius. Later archaeologists re-examined that evidence, and a radiocarbon sample of 2398 +/- 44 BC has cast doubt on the astronomical reading.
