I would take anything re the Visoko complex with a very large grain of salt (the size of your fist). More sober observers have pointed out that these are natural formations called flatirons. If they were used or modified by neolithic people, we'll never know for sure how much, because the huckster 'developing' the site has put in a considerable amount of his own modifications. Some of the tunnels are ones he dug himself. The rest may or may not be ancient mines. How old? What was being mined? Who knows? This guy's a businessman with no professional training in how to dig up an ancient site. The Bosnian government is so desperate for revenue that they are letting him trample over any real archeological sites creating a spiritual theme park all for the sake of a fast convertible mark.

I sincerely apologize for the screed but stuff like this just irks me to tears. With a public so hungry for anything sacred, even a site like this pulls in the spiritually starved at the expense of genuine sites either ancient or newly created. When the money dries up, this place likely will as well. And we'll no wiser afterwards than we were before.
