20th-century sports arenas still in use in the United States, and among the best-preserved of its kind. Brad Stevens, the former Butler basketball coach who became head coach of Boston Celtics, once remarked that Hinkle Fieldhouse is "not for everybody," but continued, "But it is for somebody that appreciates tradition, somebody that appreciates history." In 2006, to celebrate Butler University's 150th anniversary, a documentary about Hinkle Fieldhouse entitled Indiana's Basketball Cathedral aired on ESPN. More recently, a $36.2 million renovation and restoration project was completed in 2014. The 2015–2016 basketball season was the first full season in the upgraded facility. Building description The exterior of the historic arena has the appearance of "a red-brick airplane hangar" and has been called "Indiana's Basketball Cathedral." Designed by Indianapolis architect Fermor Spencer Cannon, a founding member of the Indiana Society of Architects, the six-story brick arena on more than had an original seating capacity of 15,000. The expansive, cathedral-like facilities were the result of an arched-steel truss system that supported the roof and provided unobstructed views of the basketball court. Butler's fieldhouse was also among the earliest of its kind to use ramps for access to upper-deck seats. Because of its innovative construction, Hinkle Fieldhouse has served as a prototype for other indoor athletic facilities, including the design of Gainbridge Fieldhouse, home to the city's NBA and WNBA teams, respectively the Indiana Pacers and Indiana Fever. Exterior and plan The rectangular plan for the arena lies on an east–west axis with round-arch gable ends. Its steel truss system supports a three-stage monitor roof and red-brick walls resting on a poured concrete foundation. The three-story main facade (south wall) is constructed of brick on a concrete foundation. A stone belt course surrounds the structure between the first and second stories. Decorative buttresses vertically divide the main facade into twenty-two bays. There are eight entry gates on the south wall with tall, round-arch windows above the entry doors. The north wall is similar to main facade, but it does not have entry gates. The east facade has a round-arch gable about six stories tall, as well as nine bays divided by buttresses. The west facade is identical to east wall above third floor; however, a two-story brick wing is attached to the west wall at its lower levels. The arena's exterior still retain its original features, but the steel-framed windows and metal doors have been
