>The gallows at Fort Smith served as an instrument of federal justice for 23 years, from 1873-1896. During those years, 86 men were executed for capital offenses.
>While the gallows that stands today is a reconstruction, visitors are still drawn to the place where these executions were conducted. Perhaps no other place in Fort Smith illicits such interest and strong feelings.
