The ancient stones above the valley
Blaauboschkraal Stone Ruins
(Adam’s Calendar)
African cultural landscape of the Bokoni people
Perched on the Mpumalanga escarpment between Kaapsehoop and Emgwenya lies a circle of ancient dolerite stones that has captured the imagination of historians, archaeologists, spiritual practitioners and travellers alike.
Popularly known as Adam’s Calendar, the site is officially recognised as part of the Blaauboschkraal Stone Ruins, a significant component of the wider Bokoni cultural landscape that extends across the escarpment. It is also known in contemporary African spirituality as Inzalo y’Langa — Birthplace of the Sun.
More than an isolated monument, Adam’s Calendar is a living heritage site where archaeology, African history, geology and spiritual meaning converge.
Explore the Trail →Archaeological & Cultural Landscape Context
Adam’s Calendar forms part of the broader Blaauboschkraal Stone Ruins, embedded within the extensive Bokoni cultural landscape of Mpumalanga. From the 1500s to the early 1800s, the Bokoni built a busy, inhabited, agricultural world — not a solitary stone circle.

Did You Know?
Archaeologists identify the stone circle as one of thousands of Bokoni farming enclosures across the escarpment — its walls, cattle kraals and terraces mark a lived-in agricultural landscape, not an astronomical observatory.

What the Science Says
The walls are built from dolerite (also called diabase) — a hard, dark volcanic rock — stacked without mortar into circular homesteads linked by long stone-walled passages. Dating them has taken patience: the escarpment’s soils preserve little organic material, so radiocarbon rarely works here. Instead, luminescence dating of pottery and sediments at nearby Bokoni homesteads at Komati Gorge placed them between roughly 1489 and 1765 CE — firmly in the Late Iron Age.
Archaeologists and heritage specialists recognise the stone circle as part of the Late Iron Age Bokoni settlement system. The site drew international attention in 2003 when pilot Johan Heine photographed the stones from the air — but the evidence points firmly to an African agricultural landscape.
- Stone architecture matches known Bokoni building styles across Mpumalanga.
- Walls, terraces and enclosures align with dozens of surveyed escarpment sites.
- Settlement layout — cattle kraals, terraces and stone cattle-tracks — matches known Bokoni farming sites across the escarpment.
- Oral histories place Pedi, Ndzundza Ndebele and Koni communities here into the 18th–19th centuries.
In short: Adam’s Calendar exists within a known African archaeological context, not outside it. Alternative theories remain speculative and unsupported by the evidence.
Visiting the Site
These guidelines help ensure the site remains protected, respected and accessible for future generations.
Living Culture & Meaning
While archaeology explains the historical context, the site also holds living meaning today. During the September spring equinox, groups may gather here for:
- Sunrise observances
- Drumming and reflection
- Ancestral and seasonal rites
- African New Year–related ceremonies
These practices represent modern cultural expression rather than ancient Bokoni tradition — showing how meaning continues to evolve within the landscape.
Popularly known as “Adam’s Calendar,” the site is celebrated by some as an ancient astronomical marker. Archaeology tells a different story — of farmers, not astronomers — yet the stones clearly still hold meaning for many who visit today.
- Long known locally as stone kraal ruins; brought to wider public attention in 2003 through aerial photographs by pilot Johan Heine.
- Internationally popularised from 2007 by author Michael Tellinger as “Adam’s Calendar.”
- Alternative age estimates remain unverified.
- Archaeologists identify the ruins as part of the Bokoni (Bakoni) stone-walled farming landscape of roughly the 16th–19th centuries — one of the largest such landscapes in Africa (Delius, Schoeman & Maggs, Forgotten World, 2014).
- Current archaeological evidence places the site firmly within the Bokoni cultural landscape.
- Visitors are encouraged to explore the evidence and appreciate the site’s many layers of history and meaning.
