About
Rooted in the monotheistic Abrahamic heritage, the Baháʼí Faith affirms the essential unity of divine truth through the doctrine of Progressive Revelation. This sacred curriculum views religious history not as conflicting eras, but as an unfolding education directed by God through Moses, Jesus, Muhammad, Krishna, the Buddha, and Baháʼu'lláh.
The Baháʼí House of Worship in Wilmette, Illinois—known in Arabic as the Mashriqu'l-Adhkár ('Dawning-place of the Mention of God')—serves as the continental temple for North America. Established as an open sanctuary for all humanity, it features no pulpits, clergy, or sectarian rituals, inviting souls to commune through sacred scripture alone.
Conceived as the spiritual center of a wider humanitarian complex, the temple links inward devotion directly to outer altruism. Surrounded by formal gardens overlooking Lake Michigan, this 'Mother Temple of the West' stands as the oldest surviving Baháʼí temple in the world and an architectural wonder of light.

Featured Stories
The Borrowed Pickaxe of 1912
May 1, 1912
When ʻAbdu'l-Bahá arrived to break ground on the Wilmette bluff, no ornamental ceremonial shovel had been prepared. A local worker handed him a plain iron pickaxe, with which he struck the earth to lay the cornerstone. He proclaimed that the edifice would stand as a beacon of universal brotherhood for all peoples.

Pioneering the Earley Stone
1943
Critics initially derided the plan to build the temple using concrete, dismissing it as an industrial factory medium. Architectural sculptor John J. Earley refuted them by developing a formula of crushed quartz aggregate washed with acid. The resulting luminous panels reflected sunlight so brilliantly that observers regularly mistook them for carved marble.

Sacrifice in the Great Depression
1930s
Because Baháʼí law forbids accepting funds from outside the faith, economic collapse during the 1930s threatened construction. Rather than halting work or soliciting commercial loans, believers worldwide contributed modest pennies, jewelry, and handwoven textiles. This collective sacrifice enabled builders to assemble the complex superstructure debt-free.

The temple is the dawning-place of the praise of God, open to every race and nation.
Following the construction of the world's first Baháʼí temple in Turkmenistan, American believers petitioned ʻAbdu'l-Bahá to build a sanctuary. Corinne True selected an elevated bluff overlooking Lake Michigan, and delegates gathered in Chicago to form the Bahai Temple Unity.
1910s — Groundbreaking and World Crisis
In 1912, ʻAbdu'l-Bahá visited Wilmette to dedicate the grounds and set the cornerstone before a diverse gathering. The outbreak of World War I soon suspended international communication, though regional communities continued accumulating donations.

Delegates selected the plaster model of architect Louis Bourgeois for its innovative synthesis of world architectural traditions. Engineers sank nine massive caissons 120 feet into solid limestone bedrock to anchor the temple against lakeside sands.
1930s–1940s — Superstructure and Material Mastery
Construction advanced through the Great Depression through phased contributions, completing the primary concrete skeleton. Sculptor John Earley developed patented exposed-quartz concrete panels that were installed over the dome following World War II.
1950s — Dedication of the Mother Temple
Interior finishes designed by Alfred Shaw were finalized with sound-absorbing plaster tuned for vocal singing. On May 2, 1953, the temple was dedicated for universal public devotion in a ceremony welcoming thousands of international guests.
