John Brown's Fort, Harpers Ferry

John Brown's Fort was originally built in 1848 for use as a guard and fire engine house by the federal Harpers Ferry Armory in Harpers Ferry, Virginia (since 1863, West Virginia). An 1848 military report described the building as "An engine and guard-house 35 1/2 x 24 feet, one story brick, covered with slate, and having copper gutters and down spouts…"
The building achieved fame when it became John Brown (abolitionist)'s refuge during his 1859 raid on Harper's Ferry. It is the only surviving building of the Armory; the others were destroyed during the Civil War.

The building quickly became a tourist attraction; the words John Brown's Fort—a new name—were painted over the three doors, to attract tourists. It has been moved four times: in 1891 to the World's Columbian Exposition in Chicago, in 1895 to the Murphey Farm near Harpers Ferry, in 1909 to the campus of historically black Storer College in Harpers Ferry, and in 1968 by the National Park Service to its present location in lower Harpers Ferry, near its original site. An obelisk stands where it was originally located. The building and obelisk are part of the Harpers Ferry National Historical Park.

In 2016 the building was honored with a U.S. quarter.
