The Arabia Steamboat Museum is a history museum in Kansas City, Missouri housing artifacts salvaged from the Arabia, a steamboat that sank in the Missouri River in 1856. The 30,000-square-foot museum opened on November 13, 1991 in the Kansas City River Market. The partners of River Salvage Inc., who excavated the Arabia and opened the museum, claim to have the largest single collection of pre-Civil War artifacts in the world.[2]
