A new study led by Vahe Gurzadyan of Yerevan State University offers a clearer explanation for Armenia’s ancient dragon stones, finding that the monuments were purposefully placed and constructed with manual labor rather than left at random.
The paper, published in npj Heritage Science, links the carved stelae to water sources and shows a distinct pattern in their mountain placement.
Researchers surveyed 115 vishaps across Armenia. They combined GPS and GIS mapping, photogrammetry, 3-D models, and targeted excavations at the Tirinkatar site.
The team measured each stone and recorded its elevation. They then applied statistical regression and Gaussian fits to test the relationship between stone size and altitude.
Researchers linked the dragon stones to water and mountain placement
The analysis produced two principal results. First, vishaps cluster near springs, lakes, and traces of prehistoric irrigation. Fish-shaped stones appear more at higher elevations, reinforcing the water connections.
The Armenian Highlands are home to around 150 dragon stones, or vishapakar, massive basalt monuments dating back over 4,000 years. Of these, 90 are found within Armenia’s borders.

Second, the altitude distribution reveals two distinct peaks at approximately 1,900 meters (6,234 ft) and 2,700 meters (8,858 ft). Large, heavy monuments appear at both levels. That suggests builders carried out substantial work even where seasonal access was limited.
The study treats stone size as a measure of labor. Quarrying, shaping, and hauling heavier monoliths demanded more time and people. The presence of large stones at high altitude indicates deliberate investment in those sites.
Gurzadyan said the scale of effort points to functional or ritual importance, especially tied to mountain water that feeds lowland valleys.
Limitations in dating and statistics, and recommended next steps
The authors also present important caveats. Radiocarbon dates from Tirinkatar place at least two vishaps around 4200–4000 BCE, but the team warns that these dates cannot automatically be applied to all monuments.
Many stones were found moved or only a few feet from their original positions, and displacement could bias spatial results. Orientation claims rely on a small number of reconstructable examples and remain tentative.
The paper’s statistical reporting is clear on primary fits, but the authors acknowledge gaps. The study reports R² values and Gaussian peaks but lacks confidence intervals and tests of formal multimodality and spatial autocorrelation in the published text.
Researchers call for expanded radiocarbon sampling, fuller statistical diagnostics, and public archiving of raw GIS and measurement data to ensure reproducibility.
By tightening claims and stating limits, the authors aim to avoid overreach while keeping the core interpretation: these monuments reflect organized effort tied to water management and ritual.
The study reframes Armenia’s ancient dragon stones as useful markers in a long-lived mountain landscape and urges further sampling and transparency to confirm the patterns.
