There's The Dream Mine, which is visible from I-15, just south of Provo.
The Dream Mine, or Relief Mine, is a mine in Salem, Utah, built by John Hyrum Koyle in the 1890s and incorporated in 1909. Koyle prophesied that the mine would provide financial support for members of the Church of Jesus Christ of Latter-day Saints (LDS Church) just before the Second Coming of Jesus Christ. Koyle's prophecies were controversial among leaders of the LDS Church, who excommunicated him in 1948.
Koyle died in 1949 and work on the Dream Mine ended in the 1960s, and the mine has not produced any valuable metals. However, Koyle's followers, known as "Dream Miners," have continued to maintain the mine and to trade stock in it. They believe that the mine will produce gold before the Second Coming and that Koyle's other prophecies will be fulfilled.

Then there's Gilgal Gardens.
The famous Joseph Smith Sphinx.Thomas Child, a masonry contractor and Bishop of the 10th Salt Lake LDS ward, conceived of a symbolic sculpture garden that would be a retreat from the world and a tribute to his most cherished religious and personal beliefs.[1] He began building the garden in the backyard, when he was 57 years old, and continued to pour his time and money into the work until his death in 1963. Child named the garden Gilgal after the Biblical location where Joshua ordered the Israelites to place twelve stones as a memorial. The name "Gilgal" is sometimes translated to mean "circle of standing stones," an appropriate appellation for a sculpture garden. Gilgal is also the name of a city and a valley in The Book of Mormon, a sacred scripture in The Church of Jesus Christ of Latter-day Saints.

Now, there is the proposed 40 acre Book of Mormon Park.
The proposed "Monument of the Americas" park includes plans for a visitors center and amphitheater.Latter-day Saint plastic surgeon and artist Steven Neal says nearly 30 years ago he received a vision: Images depicting stories from the Book of Mormon formed in his mind with the understanding that he was to sculpt them and someday make them available to the world.
Other textual sources he plans to feature include the Mayflower Compact, as well as several he discovered through the writings of Tim Ballard. Neal said he does not agree with all the conclusions Ballard draws in his books, which have been panned by historians. Nonetheless, he said, he feels “indebted” to the embattled anti-human-trafficking activist for introducing him to historical documents.
The crown jewels will be a monument featuring an 18-foot Jesus standing atop a depiction of the plates church founder Joseph Smith said he used to translate the Book of Mormon, with the Earth below them. On the opposite side of the park will stand a similarly larger-than-life depiction of Book of Mormon warrior-prophet Captain Moroni. Inspired by the iconic World War II photo of Marines raising the flag on Iwo Jima, the statue shows Moroni holding the “Title of Liberty,” a declaration of freedom taken from the Book of Mormon, while George Washington and U.S. soldiers offer support.
The grounds will also feature an amphitheater, as well as a neoclassical building that will double as a visitors center and an event space available for rent.
