It began as a small settlement in the mid 1800's called Pleasant Green. Mining activity came to the scene at the turn of the century and once the foundations of a modern town were laid, the name was changed to Magna in 1906. Historic Magna Main Street has served as the heart of the community and a commercial center for decades, and the local economy fluctuated along with the fortunes of the copper mine. Magna is home to major employers Rio Tinto and ATK. Between the copper and rockets that workers at these companies produce, Magna's efforts can be seen all over the world and even in space. Several films and television shows have filmed in Magna, from Disney movies and episodes of Touched by an Angel, to a Stephen King miniseries. With the township boundaries lies a portion of the Great Salt Lake and the historic Saltaire concert hall. Magna is best represented by the hard working and down to earth people that reside here.
