The Sonnentag Event Center and John & Carolyn Sonnentag Fieldhouse at the County Material Complex (The Sonnentag), scheduled to open in the spring of 2024, will provide sports and event spaces that will serve UW-Eau Claire intercollegiate athletes and students, the Eau Claire community, and outside rental groups. The multi-use facility will be the largest indoor event venue in northwest Wisconsin. UW- Eau Claire alumni John and Carolyn Sonnentag and their family foundation donated a historic gift of $70 million and land to fund the project. In addition, UW-Eau Claire students passed a referendum in 2021 supporting a fee of $90 per semester for use and maintenance of the complex. Project partners include Blugold Real Estate, Mayo Clinic Health System in Northwest Wisconsin, city of Eau Claire, Visit Eau Claire, and UW-Eau Claire. The Sonnentag will replace Zorn Arena and transform sports and entertainment opportunities for the University and the broader community. CENTERS will lead day to day operations of The Sonnentag, partnering with the University to support internal events such as athletics, recreation and graduation, as well as marketing the facility to the external market for live events and concerts, performances, rentals, and more.
