Built in 1897, this is the largest refracting telescope in the world. The grounds are original to the landscape plan of 1898.

Free tours on Saturdays at 10:00am, 11:00am, and 12:00 (noon).

Yerkes offers viewing in small groups n=15 at various times of the year through the 24 inch reflecting telescope at night. It is a awesome treat to be one on one with a astronomer and seeing the universe; well worth the $25 admission. For information call 262-245-5555, extension 832 for list of dates. Dress for the outdoors.
