An architectural building block is formed of light transmitting, molded plastic material to resemble a common glass block or brick and comprises a plurality of hollow half members joined together along a seam to form a hollow block enclosure with the seam spaced intermediately between a pair of opposite planar outer side faces of the block. Each half member has an inner surface and an outer surface comprising one of the outer side faces of the block integrally joined around its periphery to an inwardly directed peripheral edge flange having a free edge providing one joining edge of the seam. At least one of the outer opposite side faces of the block is provided with a thin, hard, transparent, abrasion, chemical and ultraviolet light resistant protective coating of plastic resin permanently bonded to an outer side face of the block to provide protection from the environment and weather.
