Abstract— The resonance phenomenon in Ravne tunnels in Bosnia – Herzegovina is an unusual but unknown phenomenon. A number of researchers consider this structure to be an ancient
mine. But in our research we demonstrated a very strong response at 71,57Hz when a singer sings inside the tunnel. Our thesis is that this structure was also used for rituals and prayers,
because the resonance of these frequencies can have a direct effect on the human body, in the same way as was found in ancient Neolithic temples in South of England.
