While Salt Lake City is known worldwide as the headquarters of the Church of Jesus Christ of Latter-day Saints (the Mormon or LDS Church for short), there is actually considerable religious diversity in the area. From the arrival of the U.S. Army and subsequent miners and tradesmen, Protestant, Catholic, and Jewish individuals began to live here and soon began to hold religious services.

Church buildings of various denominations soon proliferated, and a photographic record of them now exists in the various historical collections hosted by the Marriott Library. Some of these historic buildings still stand, though they may have been repurposed. The recent immigration of people from the Middle East and Asia has further enriched the religious landscape of the Salt Lake Valley.
