The water of the springs and river Loutanis is channeled into a tunnel through which it is led to the lake. On the way... The tunnel was constructed by Italian constructors and local workers and was completed in 1931. Its construction, as that of all public works in the area, began in the 1920's. It is 150 metres long and 13 metres high and leads the water of the seven springs and river Loutanis to a lake created by a dam. In the middle of its length, there is a well used as an airshaft. Walking through the tunnel, feet in the water, makes visitors feel that they have slipped into another dimension. It is a unique and unforgettable experience.
