Completed in 1995, the 80,000-square-foot William A. O'Neill Athletic and Convocation Center acts as a multi-purpose athletic facility for the Westside campus and houses many of Western's athletic and recreational offices. Equipped with a weight room, swimming pool and locker rooms, the O'Neill Center also contains the Feldman Arena, where Western's basketball and volleyball teams hold home competitions. The arena can seat 4,500 spectators and is often used for concerts, keynote speakers and a variety of college shows.
