Built in 1891 to house St. Augustine's worst criminals, this historic jail house is listed on the U.S. National Register of Historic Places. Today it operates as a museum, allowing visitors to see historic weaponry used and photographs taken during its 60-plus years of operation. Designed to look like a Victorian home to blend in with the surrounding buildings, the jail's dark and foreboding interior offers a stark contrast where numerous prisoners lived out their last days. Regular tours are given by day, and by night, ghost tours take adventurous visitors through the reportedly haunted building.
