"Trophy" may be too strong a word for this apparently abandoned behemoth: a concrete block, presumably of Portland cement, standing near seven feet high and about five feet wide, featuring a high relief of some sort of Greco-Roman figures, and the inscription: "Awarded Trinity Portland Cement Company Houston Texas Plant for a Perfect Safety Record in 1929." The block was re-awarded, and re-inscribed, for perfect safety records in 1945, 1947, 1959, and then, silence -- Trinity Portland Cement Company appears to have been Dallas-based, and the Houston plant was shuttered in 1975. How long it took the site to degenerate to its present state -- at the intersection of two abandoned roads to nowhere, scattered with illegally dumped trash, no sign at all of a cement plant -- is anyone's guess, but still the monument stands, too heavy to move, in silent remembrance to those few special years when no one got crushed in the machinery.
