Up the road from Evanston in Wilmette is the most visited of all the sights in the northern suburbs, the Baha'i House of Worship, an ethereal edifice that seems not of this earth. The gleaming white stone temple, designed by the French Canadian Louis Bourgeois and completed in 1953, is essentially a soaring nine-sided 135-foot dome, draped in a delicate lacelike facade, that strongly reveals the Eastern influence of the Baha'i faith's native Iran. Surrounded by formal gardens, it is one of seven Baha'i temples in the world, and the only one in the Western Hemisphere. The dome's latticework is even more beautiful as you gaze upward from the floor of the sanctuary, which, during the day, is flooded with light. Temple members offer informal tours of the building and exhibits to anyone who inquires. Allow a half-hour.
