In 1920 the American Bahá'ís chose Louis Bourgeois's design for the House of Worship at Wilmette. He then showed his drawings to 'Abdu'l-Bahá, who called the design "the most beautiful in the world."
In 1903 the Bahá'ís of Chicago asked 'Abdu'l-Bahá's permission to build a House of Worship in America. Shoghi Effendi traces the forty years, through economic crisis and war, until its eighteen outer steps were set in place in December 1942.
