Saving Our History

Saving Our History

The C&O Canal is considered to be the best-preserved 19th century canal in the United States. The men of the Civilian Conservation Corps originally restored the first 22 miles of the canal in the 1930's. Since becoming a national historical park in 1971, the NPS has worked to protect and preserve over 1300 historic structures along the canal.

Major restoration work has been undertaken at several locations including the Catoctin and Monocacy Aqueducts, Big Slackwater, multiple locks and lockhouses, and the Widewater area. There are ongoing preservation maintenance projects occuring throughout the park all year around.

C&O Canal National Historical Park also develops partnerships with individuals and organizations interested in helping to rehabilitate some of its historic structures, according to the Secretary of the Interior's Standards for the Treatment of Historic Properties.
