Santa Clara is a town / city in Washington County, in southwestern Utah, (Western United States) and is a part of the St. George Metropolitan Area.

In the fall of 1861, Swiss immigrant members of The Church of Jesus Christ of Latter-day Saints (Mormons) arrived at the new settlement.

Shortly afterward, in early 1862, they were victims of a severe flood in the Santa Clara River valley that destroyed the fort and most other buildings, along with already existing irrigation dams and ditches.

Swearing to avoid such a risk again, Hamblin built a new home on a hill in Santa Clara.

19th century Santa Clara was largely inhabited by immigrants who had earlier converted to Latter-day Saints faith in Switzerland of Europe and subsequently crossed the Atlantic Ocean and westward-moving across the North America continent to come to Utah.

[citation needed] Among these was Daniel Bonelli, who after the 1862 flood became a pioneer colonist of St. Thomas, Nevada in the Moapa Valley.

Santa Clara is home to several sites of importance to the LDS Church and local town / county history, including the historic Jacob Hamblin Home (of pioneer settler Jacob Hamblin (1819-1886) and the old Relief Society house, built in 1907.
