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.
