kosti i artefakti u 150m dubokoj komori Visočice

Austrijanac Klaus Dona je 2011 godine najavio, da se u dubini od 150m u Visočici nalazi komora, u kojoj se nalaze kosti i artefakti, koje će šokirati cijeli svijet, kada se pronađu. (minuta 6:38)

"In this 150 meter deepness inside the pyramid, there is a room and there are bones and there is something else, I will not tell you (one hears Sam´s laughter like he knows about this). You will find it, I hope so and everybody will be shocked."
