As dusk sets in, the muezzin's call can be heard.
The next Lebanese city is so close that you can hear it here in the far north of Israel.
Wooded hills are lined up on this side of the border, a lonely road connects two villages.
There is a concrete foundation on a hill with a blue steel barrel on it.
It marks the so-called Blue Line, the demarcation line between Israel and Lebanon, which the United Nations patrols with its UNIFIL mission.
A few dozen meters in front of it, Israeli soldiers guard a heavy steel door in a rock wall.
Usually it is closed.
It will be opened for this visit.
Behind it, a dimly lit tunnel screws its way down.
Slippery stone steps lead 79 meters below the surface of the earth.
