In 1847, Brigham Young led thousands of Mormons on an exodus from Illinois to Salt Lake Valley. When he arrived at present-day Salt Lake City, he declared, “Here we will build a temple to our God.” That proclamation grew into Temple Square. The three most impressive buildings dedicated to The Church of Jesus Christ of Latter-day Saints are the Salt Lake Tabernacle, the Assembly Hall and the Salt Lake Temple seen here in front of a reflection pool. This architectural gem opened in 1893 after forty years of construction.
