Nowadays Salt Lake City is the headquarters of The Church of Jesus Christ of Latter-day Saints (the L.D.S. or Mormon Church). The Mormon Temple (The Temple of Latter-day Saints) is the most characteristic building of the city.

By law no building in the city can be higher than that temple and, moreover, all streets in downtown are called "South/North/West/East of Temple".
Under the Banner of Heaven written by Jon Krakauer gives a good introduction to the history of the Mormon Church and its structure today. This book reads as good as a criminal (well, actually at least in parts it IS a criminal...) and presents very interesting views on religious systems in general. Read it if you have time.
