                The East tower is the biggest. Its 
				base forms an oval which exceeds 10 meters (30 feet) in its 
				largest diameter. It is equipped with hoardings on its outer 
				side, intended to batter the bases of the walls.
				 The junction between the wall and the wooden tower is covered 
				with shingles intended to prevent water infiltrations.

                The West tower is smaller (its 
				largest diameter hardly exceeds 8 meters). It is not hoarded but 
				its first level receives a ballista which was fired through 
				mantlets (wooden shutters).
				 Its roof is covered with freshly-cut animal skins to prevent 
				fire.
