Moonlight tours were back by popular demand in 2016, after a successful initial run during the Chicago Architecture Biennial in 2015. These exclusive tours started at dusk and returned after dark, lasting approximately 90 minutes. Guests were led along a lighted path with woods on one side and the Fox River on the other, to enjoy a full guided tour of Mies van der Rohe’s Farnsworth House illuminated against the evening sky. Moonlight tours were available May through October.
