Sonnentag Event Center is a multipurpose arena in Eau Claire, Wisconsin located near the University of Wisconsin–Eau Claire's campus. The stadium is anticipated to open in 2024. The stadium replaced the Zorn Arena.
In 2014, alumni John and Carolyn Sonnentag gave more than 25 acres of land along the Chippewa River to the UW-Eau Claire Foundation. The UW-Eau Claire Foundation also accepted a $70 million gift from the Sonnentags and their family foundation in 2021. These gifts were intended to help the university replace Zorn Arena and provide value to the community.
On July 9, 2021, the University of Wisconsin System Board of Regents authorized UWEC to lease space at the arena for 20 years with a 10-year renewal option.[6]
The stadium will host the Eau Claire Jammers in The Arena League, expected to begin in June 2025. The league agreed to a three-year lease with the stadium.
The arena will be able to accommodate all types of events. The facility will be 172,502 square feet and designed for trade shows, concerts, and competitions.
The John and Carolyn Sonnetag Fieldhouse is an 81,300 square-foot space that features a 120-yard artificially turfed field.[7]
