Williams Fieldhouse at the University of Wisconsin-Platteville serves as the home facility to the Pioneers' volleyball and wrestling programs.
Williams Fieldhouse was named for William H. Williams, a mathematics professor for 42 years (1897-1939) and the chairman of the Athletic Committee and Boards for 35 years.
The current Williams Fieldhouse Complex, in addition to volleyball and wrestling, serves as the host to offices for the UW-Platteville intercollegiate athletics, intramurals programs and club sports department. It is comprised of three connected buildings: The original 1959 Physical Education & Health Building, the 1989 Williams Center Physical Education Addition and another addition that came in 2009. The building also serves as the home to the Department of Physical Education and Health.
The 2009 season brought the addition of new seating that features 11 rows of 46 chairback seats on one side with additional bleacher seating above it. The other side is all bleacher seating with a large orange UWP integrated into the blue seats on the other side. The arrangments feature wider aisles and better hand-rails, 16 ADA-compliant wheelchair seating spaces and a larger video platform. Of comfort to families with small children, the structures eliminate the large gaps that existed between rows in the previous bleachers.
The floor was re-dedicated in 2007 as the Bo Ryan Court, in honor of the former Pioneer and current Wisconsin Badger coach who led UW-Platteville to NCAA Division III national championships in 1991, 1995, 1998 and 1999. Prior to the 2010-11 season, a new paint job was done to the floor and midway through the 2011-12 season, a brand new Daktronics scoreboard was added. Following the 2011-12 season, new energy-efficient lights were installed.
In 2011, UW-Platteville served as the host to the WIAC Wrestling Championships.
