Built around 1840, this cabin is said to have been used as a slave cabin by a previous owner on a farm in Valle Mines, St. Francois County. Around 1870, Salim Grandjean, a Swiss immigrant, gold miner, and wagon maker, purchased the farm from his uncle and transformed the cabin into a grainery. It was later donated to the Valle Mines Historic Department by Mrs. Tara Parkhurst, and the St. Louis Exhibit reconstructed it in memory of Ellis Grandjean.
