Two-thousand-year-old wooden beams lie on the sea floor in Caesarea’s harbor. These beams were part of a wooden frame into which concrete was poured in order to make immense concrete foundation blocks for the breakwater. Behind the measuring stick is the north face of the concrete block located at the northwest corner of the northern breakwater. The block measures 39 feet wide by 49 feet long by 5 feet high and was originally higher. Running along the lower edge of the block and continuing beyond the block to the right is one wooden beam; perpendicular to it, coming out toward the viewer to the right of the measuring stick, is another beam. Both are 11 inches wide and cross in a lap joint.
