The history:

"Grant Memorial Hall was constructed in 1887 to serve as an armory and provide space for military drill practice and other activities. It was named in honor of the recently deceased President, Ullyses S Grant, a civil war general. Grant Memorial Hall, also called the Armory, included a bowling alley on the ground floor, and a gymnasium on the second floor. Lieutenant John J. Pershing, Commander of the Cadet Corps, conducted training exercises in the Grant Hall gymnasium during his years at the University, 1891-1895. The original building had no heat and the interior was unfinished until an addition was completed in 1900."

Razed in 1966.
