During the Bronze Age, parallel channels were cut in the rock, sometimes in single pairs, other times in groups.

The distance between the channels varies, but the average width is 1.4 metres centre to centre, with an average depth of about 8 to 15cms.

Many different theories about their uses have been devised; some believe that they were used to carry soil from the valleys up to the hilltops in order to make fields along the slopes and on the plateaux. Some say they were man-made channels for transporting stones and soil to build terraces, while others suggest that they were a means of communication between settlements. Other suggested uses are that they were a road system between the Phoenician - Punic settlement, used as irrigation channels for the distribution of water from springs up to the agricultural terraces, used by decorated ceremonial carts or were used as trails for the carrying of megalithic blocks in order to build the temples.
