Salt Lake Temple, the principal temple on Temple Square in downtown Salt Lake City, was dedicated in 1893 after forty years of construction and became the centerpiece of church headquarters and a major historic destination. Brigham Young marked the site in 1847, and the cornerstone was laid in 1853. Designed by Truman O. Angell, the temple combined Gothic and Romanesque elements and overcame major construction difficulties, including a buried and later replaced foundation. Built of quartz monzonite from Little Cottonwood Canyon, it is the largest Latter-day Saint temple by floor area, serves sacred ordinances and church leadership meetings, and has undergone a major seismic renovation since 2019.
