No less impressive, and engineering of ancient builders. Horizontal tunnel is not only a small slope, guiding the flow of water, but also a lot of twists and turns, envelopes solid rock. Until now, no one can say how the two teams, punch a tunnel with different ends and met in the thick mountain. 
Most of the tourists when traveling through the tunnel to remain silent, those who gave their thoughts and feelings. Quietness disrupted avalanche sprinkled on the guide's questions: "Where is the sign?" The point is that the middle of the tunnel was already long passed. 
"Once she was here," - replied the guide and explained that in the tunnel it is no more. The inscription was discovered at the time when Jerusalem was under the rule of the Ottoman Empire and the Turkish authorities ordered to cut a piece of the rock with the inscription, and bring him to Istanbul. 
This was the only disappointment in the exciting journey under the earth, but I filled in the gap during one of my visits to Turkey, where specifically went to look at an ancient inscription.
