| A Bahá'í House of Worship, sometimes referred to by its Arabic name of Mashriqu'l-Adhkár (Arabic: ???? ???????), is the designation of a place of worship, or temple, of the Bahá'í Faith. The teachings of the religion envision Houses of Worship being surrounded by a number of dependencies dedicated to social, humanitarian, educational, and scientific pursuits, although none have yet been built to such an extent. Designed by Louis Bourgeois, the Bahá'í Temple in Wilmette, Illinois, was completed in 1953; the Wilmette House of worship is the largest and the oldest surviving Bahá'í Temple. The Mother Temple of the United States, it stands in north suburban Chicago, on the shores of Lake Michigan. The cladding is made out of white portland cement concrete with both clear and white crystalline quartz aggregate. It has received numerous design awards, and is a prominent Chicago-area landmark. It is on the National Register of Historic Places. Reference |  |
