The Emanu-El congregation erected the first synagogue in Spokane and the state of Washington on September 14, 1892. The city's first mosque opened in 2009 as the Spokane Islamic Center. Spokane, like Washington and the Pacific Northwest region as a whole, is part of the Unchurched Belt, a region characterized by low church membership rates and religious participation. The city serves as the seat of the Roman Catholic Diocese of Spokane, which was established in 1913, and the Episcopal Diocese of Spokane, established in 1929. The Spokane Washington Temple, established in 1999, serves Latter-day Saints from the east of the county.
