Dry Stone Workshop
September 4-5, 2013
Instructor Neil Rippingale

The Dry Stone workshop on September 4th and 5th took place at the Antietam National Battlefield and focused on restoration of dry stone walls on-site. The Battle of Antietam, which pitted the Army of the Potomac under the command of George McClel-lan against Robert E. Lee’s Confederate brigades, resulted in the single bloodiest day in American military history. Although considered a draw, the Confederate retreat at the end of the fighting allowed Abraham Lincoln to claim victory and led to the issuing of the Emancipation Proclamation. The workshop will be led by famed dry stone mason Neil Rippingale, assisted by Jane Wooley, from the Kentucky Dry Stone Conservancy.

Neil Rippingale is the Training Program Manager for the Dry Stone Conservancy in Lexington, Kentucky. Neil is a Master Craftsman certified by the Dry Stone Walling Association of Great Britain.
