The destination for pilgrims for over 600 years, this monastery houses a painting of the Virgin and Child thought to have been painted by St. Luke. We tour a 15th century library, discover the three essential elements that connect an image to a miracle and what gives an image its supernatural powers. We also find out what makes places like the Vietnam Memorial, The Alamo, our Civil War Battlefields, and Abraham Lincoln's Birthplace popular locations for a pilgrimage.
