Preliminary Report December 2010 - Excavation’s Diary


TAG: pyramids Bosnia, Bosnian pyramids, Visoko civilization, pyramids, archeology, artifact, Ravne tunnels, Pyramid Sun

I made this report in order to show what I've found when I arrived in Visoko and what we have done during the period from 3th of December until 16 of December 2010.
When I arrived in Visoko they have just discovered the new empty tunnels and they have stopped the work in order to wait for me.
For that reason I had the opportunity to make a scientific documentation
from the beginning.
We are going on with two different excavations: one in the end of the tunnel and one in a new tunnel on the right, near the entrance. First of all I want to present the new empty tunnels and the new wonderful structures we have found inside them.


That’s the entrance of the new empty tunnels


This discovery is very important because we are in front of the first empty space inside Ravne Tunnels and we have the opportunity to see the original shape of the structure.
Of course we are trying to keep the original shape everywhere but, for safety reasons, sometimes is necessary to enlarge the tunnels.
From the hole you can see in the first picture we can catch up the two new tunnels: one goes in the south-west direction and one follows the southeast.


Ravne Labyrinth


It’s impossible to go inside these new tunnels with instruments because the bottom is covered by water but, in February, I will investigate the areas with the Italian speleologist Marco Marantonio. We’ll prepare a map of the new tunnels and we’ll be able to obtain draws for the new structures.
I’ve decided to excavate the tunnel that fallows the south-west direction cause, inside this empty space, we can find the biggest structures inside Ravne Tunnels.
Maybe, in the future, we’ll go on with the investigation of the south-east tunnels, too.



That's the first drywall we can find on the right side of the tunnel. As you can see it's perfect, 90° with the floor and, as usual inside Ravne Tunnels, behind this drywall there can be another tunnel.
We can notice that this drywall is different from all the other drywalls we’ve met before: it seems that every time we go deeper inside the tunnels, structures become more precise and well organized.
Proceeding in this direction we can find other drywalls but, this time, these structures don’t seem to hide other tunnels but they can be considered like a support for the “vault”. I hope that more researches will clarify the situation.



As you can see from these pictures the structures are totally different from all the other drywalls we have discovered before. Behind these drywalls I don't think we'll find other tunnels' cause they seem to be something to
support the ceiling of the tunnels, as I’ve written before.
These new structures are made by stones and, again, they are 90° with the floor. Here we can find big rectangular blocks used to reinforce the walls.
Because of the water it’s impossible to go deeper but me and Marco Marantonio will do that during the first days of February, in order to understand how the tunnel goes on.
I took some pictures inside the south-west tunnel, too. Here we can find other common drywalls but, the most interesting thing, is what we can find in a sand layer: there are two different kind of scratches.
I don't know who or what made these scratches but my interest was to document this phenomenon.




After that I want to speak about the new tunnel on the right, near the entrance, where we started to remove the soil in order to understand the entire structure of the tunnels. We are working with the architect Lucia Krasovec Lucas (Polytechnic University of Milan – Italy) and she’s studying the organization of the area to try to capture the “logic” behind the original project.



These pictures are interesting in order to show the differences between the soil used to close the tunnels and the conglomerate.
As usual in Ravne site, we discovered four new tunnels with two new drywalls, as you can see in the pictures.


New drywall on the left, covered by the soil


New drywall on the right


The one on the left is already covered by the soil because I don't want to follow this direction, now, and I don't want to take the risk to ruin the structure.
In front of the drywall on the right we have found a big stone, set down on the floor and, later, we've discovered another stone and a third one. All these stones are in line and, the last one, seems to go under the drywall.



To protect the structures I've decided to go on with the excavation inanother tunnel near the drywall. My purpose is to catch up the “stones line” from behind. In February I will give a name to all the tunnels in Ravne site and it will be simple to speak about them cause I will be able to give precise references and we’ll create a complete map.




In this tunnel (as you can see in these pictures) we have discovered two big stones but the interesting thing is that, near the one on the right, we've discovered fire's marks!
It means that someone was there and the analysis on the organic materials we have token will tell us when. We were waiting for these marks because one of the questions about Ravne tunnels is how they could light the entire area.

That’s only the beginning but, during the winter, we’ll go on with excavations inside Ravne Tunnels and we’ll be able to publish a scientific report about the site.
