Abstract: A concrete block that can be placed in a wall constructed from a plurality of concrete blocks to accent the wall face. The block has a relief formed on a depressed field on the front of the block. The depressed field is preferably surrounded by a border that projects forwardly beyond the depressed field, and a portion or all of the relief projects forwardly beyond the border. One or more of the blocks of the invention can be placed as desired in the wall to break up the uniformity of the wall face and soften the plane of the wall, tie the wall in with the surrounding landscape, or to add interest to an otherwise uniform wall face.
