Archaeologists in Indonesia have identified a newly discovered megalith in Central Sulawesi that may be around 1,000 years old, adding another piece to the region’s long history of mysterious stone monuments.
The carved stone was discovered in the village of Toni-Toni, located within Poso Regency. The area has already been known to archaeologists for its concentration of ancient megalithic remains.
According to archaeologist Iksam Djorimi, the monument likely belongs to a later phase of the region’s megalithic culture. Researchers estimate that the stone dates back roughly 1,000 years, making it younger than many of the other monuments found in the region.
Central Sulawesi contains one of the most unusual and significant collections of megalithic monuments in Southeast Asia. Many of the most famous structures are located in the Behoa Valley and Bada Valley, where large stone statues and unique cylindrical stone containers known as Kalamba stone containers have been discovered. These monuments are believed to date back as far as 2,000 years.
Researchers have noticed an interesting geographical pattern in the region’s megaliths. As archaeological sites extend northward from the Behoa Valley toward areas like the Baru Valley, the monuments appear to become progressively younger. This suggests that the megalithic tradition may have gradually spread across different communities over time.
Unlike the Behoa and Bada valleys, northern areas rarely contain the massive stone statues or kalamba containers. Instead, they feature different types of carved stone monuments. One example can be seen in Watunonju, where researchers have documented engraved stones with distinctive carvings.
The newly reported monument was found in the Donggi Donggi area and consists of a large boulder decorated with carvings that resemble human faces. Similar carved stones have previously been recorded in the nearby Nap Valley, suggesting that the communities in these regions may have shared cultural traditions or symbolic practices.
Megaliths—large monuments made from massive stones—appear in many parts of the world and are often linked to societies from the Neolithic Period and Bronze Age. Archaeologists believe they frequently served ceremonial or symbolic purposes, such as grave markers, locations for rituals, or monuments connected to ancestor worship.
Researchers hope that further study of this newly discovered stone will provide deeper insight into the development of Central Sulawesi’s megalithic traditions and the communities that created these monuments centuries ago.
