A construction block for use with other like construction blocks to build a retaining wall. The block has substantially parallel top and bottom surfaces, and two substantially parallel sides. The front of the block is "bullet shaped," with a front nose surface being substantially perpendicular to the top, bottom, and side surfaces. Angled front sides join the nose surface to the sides, forming a 45° angle with the front and side surfaces. The rear portion of the block is generally a mirror of the front portion, with a rear surface that is substantially parallel to the front nose surface and substantially perpendicular to the top, bottom, and side surfaces. Angled rear "tail" surfaces connect the side surfaces to the rear surface at a 45° angle. The edges where the top surface joins the side and front surfaces may be beveled. At least one hole is located in the front portion of the block, passing vertically through the block from the top surface through the bottom surface. At least one hole may additionally be located in the rear portion of the block. The rear hole may be open to the rear rather than being fully closed. Multiple front holes and multiple rear holes may be provided.
