A retaining wall comprising:
- a plurality of blocks including at least one lower course and at least one upper course, at least one block comprising a block body having opposed front and rear faces, opposed first and second side walls, and opposed and substantially parallel top and bottom faces, one or more pin holes that open onto the top face of the block, and one or more lugs that extend from the bottom face, each lug having a back surface that extends contiguously from the rear face of the block.
