The Antietam Aqueduct, located at mile 69.4 of the C&O Canal Towpath, is a three-arch stone aqueduct that once carried the canal over Antietam Creek. Built in 1834, it is constructed from limestone quarried nearby and remains one of the best-preserved aqueducts along the canal. During the Civil War, it was near the site of Confederate troop movements before and after the Battle of Antietam in 1862. Though it suffered some damage over the years, it has been fully restored and now serves as a scenic and historic stop along the towpath, offering great river views and picnic spots.
