The Indiana University Natatorium: A Legacy of Aquatic Excellence
The Indiana University Natatorium, a world-class aquatic facility located on the Indiana University Indianapolis campus, stands as a testament to aquatic sports excellence. Since its completion in 1982, this iconic venue has cemented its reputation as one of the premier swimming and diving destinations globally, hosting countless nationally and internationally recognized events, and serving as a training ground for generations of elite athletes. Its impressive history is interwoven with the development of competitive swimming and diving in the United States, marking significant milestones in the careers of legendary figures and fostering a legacy of athletic achievement.
Genesis of a Champion's Arena: Construction and Early Vision
The construction of the IU Natatorium was completed in the summer of 1982, coinciding with its inaugural major event, the National Sports Festival. This ambitious project was brought to fruition under the visionary guidance of legendary IU swimming coach, Dr. James “Doc” Counsilman, who served as the lead design consultant. The facility was conceived as a state-of-the-art venue, designed to not only host major competitions but also to advance the sport itself. The initial cost of the project was $21.5 million, with the F.A. Nihelm Company contracted to build the three pools: a 76-foot by 56-foot diving pool, a 50-meter 8-lane competition pool, and a 6-lane instructional pool. The design, led by Edward L. Barnes as design architect and master planner, with Browning-Day-Pollak Associates as architects of record and Gajinder Singh as project architect, aimed to create a facility that would be a beacon for aquatic sports. The groundbreaking for the Natatorium occurred on November 12, 1980, on the Indiana University-Purdue University Indianapolis (IUPUI) campus, chosen for its central location and synergy with existing university programs. The IU School of Physical Education, now known as the School of Health and Human Sciences, moved into the facility following its completion, underscoring its dual role as an academic and athletic hub. The Natatorium was featured in the November 1983 issue of the American School and University Magazine for receiving the Louis I. This early recognition highlighted the innovative design and forward-thinking approach that characterized the facility from its inception.
A Stage for Olympic Dreams: Hosting Trials and Legends
From its early days, the IU Natatorium quickly became synonymous with Olympic aspirations. The venue has a distinguished history of hosting the USA Olympic Diving Trials multiple times, including in 1984, 1988, 1992, 1996, 2008, 2016, and 2020. Similarly, the USA Olympic Swimming Trials have graced the Natatorium’s waters in 1984, 1992, 1996, and 2000. These pivotal events have served as the crucial stepping stones for countless athletes on their journey to Olympic glory.
The walls of the Natatorium bear witness to the triumphs that have unfolded within its confines. Individuals who have qualified for an Olympic Team at the Natatorium have their name and event listed on a prominent wall behind the diving platforms. This tradition began in 1984, honoring the athletes' achievements. The facility's connection to Olympic legends is undeniable. In 1988, legendary diver Greg Louganis qualified for his fourth Olympics at the Natatorium, going on to win two gold medals at the Seoul Olympic Games. He would later compete again at the 1992 Olympic Games, further cementing his legacy. IU graduate Mark Lenzi achieved Olympic success after qualifying at the 1992 Olympic Diving Trials, winning the 3-meter springboard competition and subsequently earning a gold medal at the 1992 Olympic Games in Barcelona.
The 1996 Olympic Swimming Trials marked the third time the event was held at the Natatorium. Amy Van Dyken qualified for the team here and went on to become the first American female athlete to win four gold medals in a single Olympics at the Atlanta Games. The Synchronized Swimming Trials were also held at the Natatorium in 1996, with Van Dyken again qualifying for the team. The year 2000 saw Indiana’s own Lindsay Benko earn gold at the Olympic Games in Sydney, Australia, after qualifying at the Natatorium, and her banner now hangs above the competition pool. Michael Phelps, arguably the greatest swimmer of all time, also qualified for his first Olympic Games at the Natatorium in 2000 at the young age of 15. Phelps himself has commented on the facility, stating, "It’s always been a great pool for me to swim in." In 2008, David Boudia, who grew up training at the Natatorium, qualified for the team, setting an American record in the process, and later won a gold medal at the 2012 Summer Olympics. This marked the fifth time the Olympic Diving Trials were held at the facility. Boudia has described it as "my home turf."

Conference championships have also been a regular feature, with the Big Ten Conference Championships and Big East Conference Championships being held there.
The Natatorium played a significant role in Indianapolis's quest to be known as the "world's amateur sports capitol" by hosting the 1987 Pan American Games. During these games, nearly 4,500 amateur athletes from 38 member nations competed in 30 sports, with many of the most exciting events taking place at the Natatorium, which hosted the diving, swimming, synchronized swimming, and water polo competitions. Costa Rican swim star Silvia Poll achieved remarkable success at the 1987 Pan Am Games, becoming the first triple gold medalist to win three separate events and setting a games record in the 100-meter backstroke. Athletes from various nations also showcased their talents, with many bringing home medals for their respective countries.
In the 1980s, the Natatorium also hosted FINA World Cup events, including the Diving World Cup in 1989 and Swimming World Cup stops in 1988 and 1989, attracting top international talent and further solidifying the venue's international pedigree. The 2003 Mega Zone Championships and the 2001 World Police and Fire Games are other notable events that have been held at the facility. These events have drawn record crowds, with the 1987 NCAA Women's Championships attracting over 5,000 spectators across sessions, highlighting the facility's capacity to engage large audiences. The Natatorium has been the site of 138 American records, with many set during major competitions. The first world record at the Natatorium occurred in 1984, when Mary T. Meagher set a new mark.
Architectural and Technical Specifications: Designed for Speed and Performance
The IU Natatorium is renowned for its architectural design and technical features that contribute to its reputation as a fast pool, enabling swimmers to achieve peak performance. The main competition pool is a 50-meter, eight-lane facility, measuring approximately 25 yards in width to accommodate standard international competition standards.

The depth of the main competition pool is meticulously maintained at 9 feet at the ends and 10 feet at the center, providing optimal conditions for diving and swimming. The water temperature is consistently kept at 79 degrees Fahrenheit (26 degrees Celsius) for swimming competitions, ensuring a comfortable and performance-enhancing environment. The pool contains six underwater windows strategically placed for television and coaching analysis, offering invaluable insights into technique and performance. The main pool holds approximately one million gallons of water.
The diving well is equally impressive, featuring a dedicated 25-yard, seven-lane pool measuring approximately 76 feet long and 56 feet wide, with a volume exceeding 450,000 US gallons. Its uniform water depth of over 17 feet ensures safe entries from high platforms. The diving facilities are FINA-compliant, boasting four 1-meter and four 3-meter springboards, and five diving platforms of varying heights: 5 meters, 7.5 meters, and a prominent 10-meter tower for advanced platform diving. The diving well itself serves as a dedicated warm-up area, with a controlled water temperature of approximately 86 degrees Fahrenheit (30 degrees Celsius). The diving facilities were engineered by Kiefer McNeil (formerly Adolph Kiefer & Associates), incorporating innovations like optimized pool gutters and surface design to minimize splash on entries while prioritizing diver visibility and safety, crucial for high-risk dives.
A unique design element contributing to reduced water turbulence is the filtration system located beneath the pool floor.

This new 5,095-square-foot fitness garden features 33 fitness stations, picnic tables, benches, and greenspace, adding another dimension to the facility's offerings.
A Multifaceted Facility: Beyond Competition
While the IU Natatorium is celebrated for its competitive prowess, it also serves a broader community role. It houses various swimming clubs from across the Midwest and is the venue for the annual IHSAA boys and girls swimming championships, providing a high-level competitive experience for high school athletes in Indiana.
The facility has also been integrated with academic programs. When the university was part of Indiana University-Purdue University Indianapolis, the Natatorium served as the home of the School of Health & Human Sciences, including physical education, tourism management, pre-physical and pre-occupational therapy programs, with its offices on the second level and the Polaris Fitness Center on the first level. By 2012, the School of Physical Education and Tourism Management shared facilities at the IU Natatorium. The building is divided into deck, concourse, and bridge levels, covering approximately 200,000 gross square feet. The deck level contains weight-training and conditioning rooms, the competition pools, and an instructional pool. A research suite for exercise physiology and biomechanics is also located on the deck level. The concourse level of the physical education wing contains a large gymnasium, an auxiliary gymnasium, racquetball courts, and the Informal Learning Laboratory. The bridge level contains administrative and faculty offices.
The Natatorium also offers programs for the wider Indianapolis community and IUPUI students, including classes and lap swims in its instructional pool. Furthermore, the facility has been at the forefront of aquatic rehabilitation. The water's buoyancy supports the body, making movement easier and less painful, which is ideal for individuals recovering from injury or surgery, managing chronic pain, or dealing with joint issues. This focus on aquatic therapy highlights the Natatorium's commitment to health and wellness alongside athletic performance.
The venue's commitment to innovation was further demonstrated with the integration of a moveable pool floor in its training pool, a feature that made the facility highly versatile. This floor could be adjusted to different depths, catering to a wide range of activities, from swim meet training and dive practice to rehabilitation exercises. This adaptability underscores the Natatorium's ongoing evolution and its dedication to meeting diverse needs.
