The aligning elements of the lower blocks fit into the void of the upper block and assist in aligning the upper block on the lower blocks and, optionally, in securing a reinforcing structure placed between the layers. The blocks may include aligning elements extending upwardly from an upper surface of the block body. Each block may additionally include opposing front and back body portions, and opposing side body portions, defining a void therein. The mounting surface can be embodied as a groove which is inset into the upper surface of the blocks. Each block also includes at least one mounting surface for securing a stabilizing element therewith. A block of an upper row is laterally positioned by positioning it on top of two lower blocks. The blocks are adapted for assembly to form a retaining wall system. Retaining wall blocks, retaining wall system formed thereby, and method for manufacturing the retaining wall blocks.
