Sonnentag Complex

Partnering to enhance events, health and wellness opportunities

UW-Eau Claire alumni John and Carolyn Sonnentag had a vision: A new events center to serve UW-Eau Claire and the surrounding community that can accommodate larger-scale events than what can currently be held in available area venues.

That vision is now taking shape, thanks to a generous commitment of $10 million in land and money through the Sonnentags' philanthropic foundation to the Blugold Real Estate Foundation (a supporting organization of the UW-Eau Claire Foundation) in December 2014. Learn more about the Sonnentags' gift and the plans underway for the Sonnentag Event and Recreation Complex.

Mock-up drawing of the events center

The site of the Sonnentag Event and Recreation Complex will be on Menomonie Street in Eau Claire, along the Chippewa River, on the former sites of John and Carolyn Sonnentag's family-owned business, County Materials Corp., and another company, Student Transit-Eau Claire Inc.

As currently envisioned, the complex will include:

  • an approximately 130,000-square-foot major event center with seating to accommodate 4,500-5,000 and total capacity of 5,500-6,000;
  • YMCA, UW-Eau Claire and Mayo Clinic Health System wellness, aquatics and recreation facilities of approximately 150,000 square feet;
  • surface parking to serve the entire complex; and 
  • land suitable for development of private businesses that could complement and serve activities at the event and recreation complex.
