The main phone number for the Salt Lake City, Utah, headquarters of the Church of Jesus Christ of Latter-day Saints is 1-800-537-9703, as of January 2015. Every day of the week, the Temple Square is open and offers tours.
The Salt Lake Temple, which does not provide tours, is Temple Square’s main draw. On April 6, 1853, work on the Salt Lake Temple officially began. It took 40 years to complete. Several other notable structures, including the Salt Lake City Tabernacle, which houses an 11,623-pipe pipe organ and hosts performances by the Mormon Tabernacle Choir, are also located in Temple Square.
