The Winfield Dunn Center (officially the Winfield Dunn Health and Physical Education Building and Convocation Complex) is a 132,000-square-foot (12,300 m2) facility, located on the main campus of Austin Peay State University in Clarksville, Tennessee. Construction began on the (then) $5.3 million facility in 1973, and the building opened in 1975. It is home to the Governors men's basketball team and the Lady Govs women's basketball and volleyball teams and is an indoor practice facility for the baseball, softball, and track and field teams. It also houses the athletics department's weight room and the David P. Roe Academic Services Center which was named for alumnus Phil Roe. The building was named for the governor of Tennessee at the time of its construction.
The Dunn Center features a 7,257-seat multi-purpose arena named the Dave Aaron Arena in 1988 in honor of the longtime Austin Peay athletic director and coach, Dave Aaron. In the fall of 2007, the basketball court was named the Dave Loos Court to honor the then athletic director and men's basketball coach Dave Loos. It hosted the Ohio Valley Conference men's basketball tournament in 1977.
The Dunn Center is often referred to as "The House That Fly Built", a reference to Austin Peay basketball great Fly Williams. It has also been called "The Big Red Barn," a reference to its predecessor gymnasium where Williams played (which had been built during the World War II era) that was known as the "Little Red Barn."
