Yerkes Observatory

Restoration in progress! We're open for tours, programs, observing nights (spring, summer, fall), and an array of diverse speakers. Tickets and program info is on our website. Rising from the shoreline of Geneva Lake, Henry Ives Cobb's architectural masterpiece and the Olmsted Brothers' 50-acre slice of landscaped grandeur create a symbiosis of craftsmanship and nature. Thanks to our community for your patience during our metamorphosis. The architects, designers, and tradespeople from all walks of life have taken remarkable pride in restoring Yerkes Observatory's campus to its original 19th Century splendor while rocketing it into the 21st Century and beyond for generations to come.
