Independent researcher and executive director of Serbian Research center “Duh Rtnja” Saša Nađfeji has further analyzed Klaus Dona’s map of the tunnels within the Bosnian Pyramid of the Sun. Saša noticed that inner passageways are placed one below each other, on several different levels, so “it has to be vertical connection between them”.
Both of them, Klaus Dona (Wien, Austria) and Saša Nađfeji (Belgrade, Serbia) were participants of the Second International Scientific Conference on Bosnian Pyramids held in September 2011 in Visoko, Bosnia-Herzegovina.
