A mortar-less retaining wall apparatus is built from of a plurality of masonry blocks, each masonry block having four side walls and two end walls, two or more masonry blocks being abutted on respective side walls, one of the end walls of each masonry block having a mortar-joint simulating reveal portion. One or more of the masonry blocks each has a side wall that tapers from one end wall to the other end wall, thus allowing either straight or curved walls to be built by changing the relative orientation of the tapers of adjoining blocks.
