Each academic year, UNC Visitors Center promotes a special series of campus tours — the Priceless Gems — about Carolina’s mission and history, traditions, legends and landmarks. These on-campus walking tours are led by experts on specific aspects of Carolina history. Tours are free, open to the public and last about an hour to 90 minutes. Tours begin at the UNC Visitors Center, located in the west wing of Carolina's Morehead Planetarium and Science Center at 250 East Franklin Street. These tours are an extraordinary opportunity to explore specific topics in depth with an expert in the field. The Priceless Gem Tour calendar will be updated shortly, and tours will resume later in the fall.
