The 420 foot LDS Church Office Building is the second tallest structure in Salt Lake City and the visual pinnacle of Temple Square. The high-rise has been the headquarters of The Church of Jesus Christ of Latter-day Saints since 1973. At the base are statues of Joseph Smith and his wife Emma sculpted by Florence Peterson Hansen. In 1830, Joseph published the Book of Mormon and founded the Church of Christ. It was renamed The Church of the Latter-day Saints in 1834. Tragically, Joseph Smith was killed by a mob in 1844.
