Construction blocks for use in constructing retaining walls, embankment stabilizing matrixes, planters, waterway protection walls, and similar structures include a generally C-shaped block, a straight block, a generally Z-shaped block, and a generally S-shaped block. The blocks have a center section having a length X. Except for the straight block, wings project outwardly from each end of the center section. The wings have a length ½X and extend from the centerline of the center section at an angle of 120 degrees. The blocks include grooves on their upper surfaces and tongues that project from their lower surfaces. The grooves and tongues are interconnected when blocks are superimposed so as to provide a stable structure. In addition, the ends of the wings include openings into which dowels can be inserted in order to connect adjacent blocks and thereby provide additional stability. The blocks are attractive, strong, and inexpensive to manufacture. They can be connected securely to each other without mortar. Moreover, the blocks are sufficiently compact and lightweight that they can be carried and installed by only one or two workers.
