One of the finest on-campus facilities in the country, WKU's E.A. Diddle Arena serves as the competition home of WKU Hilltopper Basketball, WKU Lady Topper Basketball and WKU Lady Topper Volleyball.
The building, named for legendary Hilltopper coach E.A. Diddle, was officially dedicated in December 1963, and underwent a $32 million renovation in 2002. The facility celebrated its 50th year of operation during the 2012-13 school year.
Included in the Diddle Arena renovation were a new playing floor, all-new seating, two "Pepsi Vision" video boards and 16 luxury suites. But those were just the changes made to the playing arena. An addition was added to the back side of the facility which houses training and weight rooms, as well as a 30,000-square foot auxiliary gym complex containing two regulation basketball courts with a firewall divider. New locker rooms and office facilities were also added for multiple sports and the athletics administration.
The utility and versatility of the arena has been amply demonstrated throughout the years. It has been the site of NCAA Regional Tournaments in both men's and women's basketball, the Kentucky High School Athletic Association's Girls Sweet 16 basketball tournament, and an NBA exhibition game.
The facility has also hosted several Sun Belt Conference basketball tournaments and was the site of the 2003, 2009 and 2012 SBC Volleyball Championship. Diddle Arena has staged numerous concerts, hosted WKU's annual spring and winter commencements, and has even welcomed the President of the United States during a 1988 visit by Ronald Reagan.
In addition to being one of the homes for WKU Athletics, Diddle Arena also contains classrooms and activity areas for the Department of Physical Education and Recreation as well as the WKU Army ROTC program.
