Latter Day Saint movement portal The Conference Center, in Salt Lake City, Utah, is the premier meeting hall for the Church of Jesus Christ of Latter-day Saints (LDS Church). Completed in 2000, the 21,000-seat Conference Center replaced the traditional use of the nearby Salt Lake Tabernacle, built in 1868, for the church's biannual general conference and other major gatherings, devotionals, and events. It is believed to be the largest theater-style auditorium ever built. From Wikipedia
