House of Worship

The Bahá'í House of Worship in Wilmette is an intricate concrete masterpiece with thoughtful details that reflect oneness for humanity.

The Bahá’í religion was founded in the Middle East in the 1840s. Its introduction in the United States can be traced back to a Parliament of the World’s Religions meeting in Chicago in 1893. By 1900, there were nearly 1,000 Bahá’ís living in the U.S. and Canada. Plans to construct a Bahá’í temple in the Chicago area emerged in 1903, but it would be another 50 years before the temple was finished.

Two lots were purchased along Lake Michigan in 1907, in what was then Grosse Pointe (now Wilmette). Raising funds for the temple’s construction proved difficult, as it was financed by individual contributions from Bahá’ís around the world. Two World Wars and the Great Depression slowed things down. The son of the religion’s founder dedicated the temple during a visit to the U.S. and the foundation stone was laid in 1920.

The architect & the craftsman

The building’s architect, Louis Bourgeois, was a French Canadian who joined the Bahá’í faith more than a decade before working on the temple.  He began his work on the structure in 1920 and moved his studio to a building across the street from the site, to be closer to his project. Bourgeois felt the design of the temple needed to reflect the Bahá’í belief of oneness for humanity, as well as the unity of all religions. In describing his design, he said, “There are combinations of mathematical lines, symbolizing those of the universe, and in their intricate merging of circle into circle, and circle within circle, we visualize the merging of all religions into one.”

The building combines neoclassical symmetry, Gothic ribbing, a Renaissance dome, a Romanesque clerestory and Islamic arabesque tracery with the suggestion of minarets. The carvings on the nine exterior pillars reference various world religions with symbols like the Star of David, crucifixes and the Islamic star and crescent. The gardens contain both rectangular approaches and circular gardens, reflecting Eastern and Western influences.

Selecting a material to realize Bourgeois’ elaborate designs proved difficult. Limestone, granite, terra cotta and aluminum were all considered before concrete was selected. One critic strongly disapproved, calling it “the most repellant object imaginable” since it lacked beauty of the surface and weathered poorly. But John Earley, a fifth generation stone carver who came from a family of ecclesiastical artists, made the concrete beautiful. Inspired by Italian pebble mosaics, Earley developed a method of exposing the larger pebbles in the aggregate of the concrete mixture. This gave the concrete a warmer appearance. On the Bahá’í  Temple he used two types of quartz to give the exterior an almost luminescent quality. The result inside and out is stunning, resulting in the structure sometimes being referred to as the “Temple of Light and Unity.”

Neither Bourgeois nor Earley saw the completed temple. The formal dedication for the superstructure took place in 1953.

The mother temple of the west

There are only nine Bahá’í houses of worship in the world. All nine temples share certain design features, including domes and gardens. Each temple is nine-sided because Bahá’ís consider the number nine—the highest single number—a symbol of oneness, comprehensiveness and unity. In Wilmette, the temple includes nine entrances and nine verses above the doors and the alcoves. Of all the temples, the Wilmette house of worship is the oldest. It has been named a National Historic Landmark, one of the Seven Wonders of Illinois and is visited by 250,000 people a year. Aside from being called the “Temple of Light and Unity,” the 1100-seat Wilmette building is known as the “Mother Temple of the West” by Bahá’ís around the world. Today, it remains the only Bahá’í temple in the U.S.
