The Salt Lake City Mormon LDS Temple and Temple Square as seen from the 26th floor observation deck on the Church Office Building. Built by the Church of Jesus Christ of Latter-day Saints, the Salt Lake Temple was dedicated in 1893, and took nearly 40 years to construct. The Church’s walls are made of quartz monzonite, quarried from Little Cottonwood Canyon to the south in the Wasatch Mountain Range that runs along the east side of the Salt Lake Valley in Utah. The temple was the 6th temple constructed following the exodus of the Mormon’s from Nauvoo, Illinois, in 1846.
