More and more volunteers, who work on archaeological locations in Visoko, leave with very positive impressions. Two of them placed their video clips from the pre-historical underground labyrinth “Ravne” on you tube.
In the comments we can read: “The tunnels are dug into a post glacial deposit. At some point in the past, these tunnels were blocked up with an unconsolidated mix of sand, cobbles, pebbles and clays.
The tunnels were not filled up with natural deposits. Here in the clip you can see workers slowly removing the material from the tunnels, moving deeper into the tunnel network and closer to the Pyramids.”
