Namoratunga is an archaeoastronomical site on the west side of Lake Turkana in Kenya, believed to have been founded around 300 BC. Namoratunga II ( contains 19 basalt pillars, aligned with 7 star systems: )Triangulum, Pleiades, Bellatrix, Aldebaran, Central Orion, Saiph, and Sirius. Namoratunga means "people of stone" in the Turkana language. Mark Lynch and L.H. Robbins discovered the site in 1978. Lynch believes the basalt pillars tie the constellations or stars to the 12 month 354 day lunar calendar of Cushitic speakers of southern Ethiopia. The pillars align with the movements of the 7 constellations corresponding to a 354 day calendar. The pillars are surrounded by a circular formation of stones. One grave with a pillar on top exists in the area. Namoratunga I ( contains a similar grave but no pillars. )
