engine. Constructed on the Gettysburg Battlefield's highest hill, the Big Round Top tower was to be replaced for the 1938 anniversary reunion by a stone "Gettysburg Peace Memorial" with a 75-foot-high observation deck above the summit and a flame 30 feet higher. a. a. (The memorial was instead erected on Oak Hill.) Destruction During 1968 tower maintenance, the Schlesser Demolition Co dismantled the Big Round Top tower as uneconomical due to "its condition and the very limited use [due to an uphill, lengthy, and serpentine trail.] Most who started the climb gave out en route, and upon reaching the tower decided against continuing the climb to the top of the metal observatory" (GNMP Superintendent George F. Emery). The foundation ruin (park structure RU05) of the "national landmark" tower, was "entered-documented" as a historic site on January 23, 2004.
