The hills near Visoko, Bosnia, are ancient pyramids
The claim: Visočica hill and neighbouring hills near Visoko, Bosnia and Herzegovina, are giant pyramids built tens of thousands of years ago, with tunnels beneath them.
Where the evidence stands: Proposed by Semir Osmanagić from 2005, with excavation and tourism since. Geologists who have examined the hills describe tilted and fractured layers of Miocene sediment, a common natural landform. No peer-reviewed study has dated construction. We record the proponents' view and the geology neutrally.
Background
The 'Pyramid of the Sun' (Visočica) has a strikingly regular triangular face. Osmanagić's foundation points to flat slab-like 'paving' and block-like conglomerate as human work, and has excavated a tunnel network (Ravne). In 2006 a group of European archaeologists objected publicly to state support for the project. Robert Schoch, the same geologist who argues for an older Sphinx, visited in 2006 and concluded the hill is natural.
What has been measured
Dates, measurements and documented findings, kept separate from interpretation.
- Field and core work by geologists found layered sandstones, clays, siltstones and conglomerates deposited in the Miocene and later tilted and fractured by tectonic forces. [1]
Proponents' main arguments and cited evidence
- Proponents point to the hills' regular shape and orientation, and to slabs and blocks they interpret as cut and placed. [3]
What evidence would help settle it
Dated, unambiguous construction features such as tool marks, foundations or bonded masonry, published with peer review, would change this entry. So would an independent geological survey that found structures sediment layers cannot explain.
Sites
Visočica hill ('Bosnian Pyramid of the Sun')
