About

Greenback Castle is a bizarre, fascinating, and polarizing roadside attraction. Visitors are often struck by the dedication of the builder, Junior Banks, and the unique, eccentric nature of the structure. While some find it a magical, must-see gem, others find it creepy, run-down, or unsettling. It is definitely an off-the-beaten-path experience that is best suited for those who enjoy quirky, folk-art style attractions.
