It famously survived multiple attempts by Confederate forces to destroy it, thanks in part to its robust construction and the actions of Lockkeeper Thomas Walter, who convinced General D.H. Hill to drain the canal instead of blowing up the structure. This resilience makes it a 'hidden gem' of Civil War history, showcasing how infrastructure played a critical role in the conflict. The aqueduct's construction from white and pink quartz sandstone quarried from nearby Sugarloaf Mountain also adds to its unique character and beauty.
