Further back, at the distance of about thirty yards, came the main line of defence, which in general character resembled the second, but was loftier and stronger.

There was, first, a third ditch (or moat, if water could be introduced), and behind it a wall thirty-five feet thick and sixty feet high, pierced by two rows of embrasures from which arrows could be discharged, and having a triple platform for the defenders.

This wall was kept entirely clear of the houses of the town, and the different storeys could be reached by sloping ascents or internal staircases.

It was flanked at intervals by square towers, somewhat higher than the walls, which projected sufficiently for the defenders to enfilade the assailants when they approached the base of the curtain.
The tombs of the Phoenicians were, most usually, underground constructions, either simple excavations in the rock, or subterranean chambers, built of hewn stone, at the bottom of sloping passages, or perpendicular shafts, which gave access to them.

The simpler kinds bear a close resemblance to the sepulchres of the Jews.
