Yerkes Observatory is Geneva Lake's most unique and exclusive venue for your wedding or special event. The Observatory is able to host a limited number of tented weddings and receptions of up to 350 guests, and offers options for intimate dinners, cocktail parties, or receptions in the historic 1897 Yerkes building, which has been extensively restored to its period splendor. Your wedding or event will take place among a gorgeous backdrop of 50 acres of Olmsted-designed grounds unlike any other site in Wisconsin. The Observatory is proud to partner with Graceful Events, the region's leader in gracious wedding planning and design.
