THE first time it was likely suggested that a temple be built in Logan, Utah was on June 29, 1873.
President Brigham Young, speaking at meetings in Logan, "suggested the erection of a fine Temple to be built on the bench crowning the eastern part of this city," according to the Salt Lake Herald Newspaper of June 29, 1873.
(At the same time, President Young suggested a road be built beyond Franklin to lessen the grade to Soda Springs and Rich County.)
According to LDS.org, the Logan Temple was not officially announced to be built for another three plus years, until Oct. 6, 1876. Its groundbreaking was on May 18, 1877 and its dedication took place on May 17, 1884.
