The city of Gubla was protected with large defensive walls that show how the use of ramparts evolved. The buttressed city walls date back to the Canaanite period (3000 B.C.) and surrounded the city. In 2000 B.C. the city walls were sloped ramparts, called glacis. They were enlarged and reinforced several times until the end of the Phoenician period. The glacis were typical Phoenician constructions, made by piling cobbles brought from the sea over a sloping beaten earth in a way that exposes the attackers to the projectiles hurled by defenders of the city.
