A specially constructed block for use in forming a mortarless retaining wall is disclosed, as is a retaining wall constructed therefrom and a method of constructing a retaining wall. Each block has a front face of a predetermined width and a rear wall having a substantially equal width. The block side walls provide a maximum block width at the front face and a minimum block width adjacent the rear wall. When such blocks are placed in a side-by-side relationship, a substantially closed cavity is formed between the blocks for receiving backfill material and thereby reinforcing the wall. A wall constructed from a plurality of such blocks utilizes an engagement clip disposed between blocks in upper and lower courses for preventing relative forward movement between the blocks. The clip is engageable with the upper surface of the rear web of the block for easy installation after the block is laid in a course. The clip engages the inner surface of the rear web of a block in an upper course, and is preferably disposed within the core of the upper block. Each block is provided with outwardly projecting ears which can be knocked off to form a wall having a radius of outside curvature, and the ears and clips cooperate to allow construction of a wall of inside curvature.

A retaining wall comprising: a plurality of stacked, individual blocks, each said block comprising: a front outer wall presenting a block face having a predetermined width; a rear wall spaced from said front wall and having a width substantially equal to that of said front wall; a pair of side walls extending between said front outer wall and said rear wall, an upper block surface; and a lower block surface; wherein each said block is provided with a core therethrough, with the area of said block disposed between the core and the rear wall of said block defining a rear web; said wall being formed by a plurality of courses of said blocks, with a joint being formed between the blocks in adjacent upper and lower courses by the lower and upper block surfaces, respectively, of the blocks forming said upper and lower courses, each said course comprising a plurality of said blocks placed in a side-by-side relationship, wherein each end of the front outer wall of each block is located closely adjacent an end of the front outer wall of its neighboring block, and each end of the rear wall of each block is located closely adjacent an end of the rear wall of its neighboring block; engagement means interposed between the blocks in adjacent courses for preventing relative forward movement between the blocks in adjacent courses, said engagement means comprising clip means mountable to the rear web of a block in one of said upper and lower courses, said clip means including a substantially horizontal portion for placement adjacent the surface of said block forming said joint, and a substantially vertical projecting portion adapted to engage the rear web of a block placed in an adjacent course for preventing forward movement of blocks in an upper course relative to blocks forming the course therebelow; and a recess formed in one of said block surfaces forming said joint for receiving the substantially horizontal portion of said clip means to prevent interference thereof with said joint, with the vertical projecting portion of said clip means projecting outwardly past said recess
