Adam-ondi-Ahman (/ˈæd.əm ˈɑːn.daɪ ˈɑː.mən/, sometimes clipped to Diahman) is a historic site in Daviess County, Missouri, about five miles south of Jameson.

It teaches that the place will be a gathering spot for a meeting of the priesthood leadership, including prophets of all ages and other righteous people, prior to the Second Coming of Jesus Christ.

It was the site of a skirmish during the American Civil War on August 4, 1862, when Union troops attempted to stop Confederate reinforcements in the First Battle of Independence.

[note 1] On May 19, 1838, Smith formally revealed his belief that Adam-ondi-Ahman was the place where Adam and Eve went after being exiled from the Garden of Eden.

In October 1838, Smith, Brigham Young, Heber C. Kimball and other Latter-day Saint leaders gathered to dedicate the temple square on the highest point on the bluff.

On April 15, following the granting of a change of venue, Smith was permitted by his guards to escape while en route to Boone County, Missouri, a day after getting supplies at Adam-ondi-Ahman.

In 1947, Wilford C. Wood purchased 38 acres in the area to begin to return the land to the LDS Church, including the location identified as Tower Hill and the remains of a cabin built by Lyman Wight.

[9] Today, 3,000 acres (12 km2) of Adam-ondi-Ahman is owned and maintained as a historic site by the LDS Church and remains largely undeveloped farmland.

Adam-ondi-Ahman is the subject of a revelation received by Joseph Smith and recorded in the LDS Church edition of the Doctrine and Covenants, a book of scripture within the Latter Day Saint movement: “Spring Hill is named by the Lord Adam-ondi-Ahman, because, said he, it is the place where Adam shall come to visit his people, or the Ancient of Days shall sit, as spoken of by Daniel the prophet.”[10] Contemporaries of Smith stated that he taught that the Garden of Eden was located in the vicinity of Independence, Missouri,[11] and that after Adam and Eve were banished from the garden, they went to Adam-ondi-Ahman.

[13] LDS Church leader Joseph Fielding Smith has written that this is the site of a future grand council where Jesus Christ will meet with His stewards of all dispensations and receive back the keys of the kingdom in preparation for His Second Coming.
