Temple Square is a ten-acre religious complex in central Salt Lake City and the historic core of Latter-day Saint Utah. Chosen by Brigham Young in 1847 soon after Mormon pioneers entered the Salt Lake Valley, it grew from a temple site called Temple Block into the center of church administration, worship, and public gathering. Its best-known buildings include the Salt Lake Temple, Tabernacle, and Assembly Hall, while later expansion reflected the church’s growing public functions. The square also became a major visitor destination, known for gardens, concerts, and Christmas lights, and its southeast corner anchors Salt Lake City’s street grid. It has been a National Historic Landmark District since 1964.
