The Apple River Fort Historic Foundation was founded over ten years ago. Dedicated members spent five years rebuilding the Apple River Fort. The original fort was the only fort attacked by Black Hawk and 200 Sauk warriors during the Black Hawk War in northern Illinois in the summer of 1832. Three women named Elizabeth are credited with saving the Fort that day as their bravery was tested when they assisted the militia in defending the Fort. The town earned it's name the day that the Elizabeths' defended the Fort. Today costumed interpreters work at the Fort recreating life in 1832 to over 30,000 visitors yearly. School tours and education programs make up a significant portion of the attendance.
