The Bosnian Pyramid, Visocica Hill, is the first European pyramid to be discovered and is located in the heart of Bosnia, in the town of Visoko. The pyramid has all the elements: four perfectly shaped slopes pointing toward the cardinal points, a flat top and an entrance complex. There are also the ruins of a Medieval walled town, once the base of a Bosnian king Tvrtko of Kotromanic (1338-1391). Because of its similarities to the Pyramid of the Sun in Teotihuacan, Mexico, it has been named the “Bosnian Pyramid of the Sun” (’Bosanska Piramida Sunca’).
The pyramid walls are built from the megalita breče stone. Blocks of different sizes are typically used to build pyramids. These stone blocks have been excavated some 150 m away from the apex of the pyramid. Further excavations are underway in the surrounding areas to map the blocks and underground tunnels.
Bosnia's mystery pyramid is to be investigated and inspected by a team of experts from the United Nations Educational, Scientific and Cultural Organisation (UNESCO).
