The Battle of Gettysburg was a turning point in the Civil War, and its battlefield has been described as one of the world's largest collections of outdoor sculpture. Members of the public may learn about these monuments and more on Thursday, July 11, from 6 to 7 p.m. during a free presentation at Senior Commons at Powder Mill, 1775 Powder Mill Road, York.

Guest speaker John Smith, a volunteer with the monument preservation program at Gettysburg National Military Park, will highlight his experience working on various methods of monument preservation and give a guided visual tour of Gettysburg's catacombs, a treasure trove of vast Civil War artifacts that most people do not get an opportunity to see.
