Shafer Tower is a 150-foot-tall (46 m) free-standing bell tower, or campanile with a carillon and chiming clock in the middle of the campus of Ball State University. Dedicated in 2002, Shafer Tower has become an unofficial landmark of Ball State University. It stands in the median of McKinley Avenue on University Green, the northern quadrangle of campus. Due to a construction defect in the type of cement used to build the tower, most of Shafer Tower had to be built twice. The architect of record was Edmund Hafer Associates of Evansville, Indiana.
