Dedicated March 30, 1909, Greenwood Cemetery contains a wide variety of twentieth-century markers and substantial mausoleum. The oak -shaded, 196-acre grounds contain the burial sites of a number of notable Fort Worth figures including the mausoleum of Amon G. Carter, Sr. There is also a monument erected to honor the Canadian flyers killed while training at Tarrant County airfields during World War I. An important structure in the cemetery is Greenwood Mausoleum, designed by Harwell Hamilton Harris; the first section was completed in 1961 with an addition in 1971. A monolithic one-story box faced in shellstone, each of its blank walls is relieved only by a central low arch and asymmetrically placed vertical fenestration band. Reminiscent of decorative treatments by Louis Sullivan, Harris’s design won an award of honor from the Texas Society of Architects in 1961.
