We revisit the C & O Canal National Historical Park in Williamsport, Maryland.

After a ten-year stint on the west coast we’ve returned to the mid-Atlantic and the first thing we did was visit some of our old haunts and favorite historical sites. One of the first places we went to was the C & O Canal National Historical Park site in Williamsport, Maryland. I did a post on the canal towpath and the park back in 2011, as well as a post about the Paw Paw Tunnel, located up the canal about thirty miles. Give that first post a read to find out the history of the Chesapeake & Ohio Canal and what it is today. Here is a pretty good video that will also give you a rundown on the history of the canal.

An aqueduct is a bridge
for water.

Okay, if you didn’t go to those sources above, let’s review. Before roads and railroads, passengers and freight were moved by water. To conquer unnavigable rivers, canals were built that included aqueducts and locks to cross rough terrain and move boats through rises in elevation. These canal projects were a product of the industrial revolution and Europe got a big head start on the United States. Our most famous, the Erie Canal in New York state, opened in 1825 (you have the song stuck in your head now, don’t you?). The C & O Canal got a late start, not opening until 1850, navigating the Potomac River from Georgetown in Washington D.C. to Cumberland, Maryland. It continued to operate until the 1920s, so through the efforts of some dedicated individuals, we have a well-preserved example of these kinds of narrow boat canals AND a 184-mile recreational trail for biking and hiking.

Now there is water in the
aqueduct at Williamsport.

So what changed since I was in Williamsport a decade ago? First off, there is a new park headquarters building just up the hill from the visitors center and the turning pond. This makes sense to me, as Williamsport is just about midway between Cumberland and Georgetown. They have also restored the aqueduct over Conococheague Creek where it flows into the Potomac. That needs a little more explanation.

An aqueduct is built to carry water. In the case of the C & O, the aqueducts were built to carry boats over existing rivers. When I visited ten years ago, the aqueduct in Williamsport was missing a wall and visitors used it like a bridge to cross Conococheague Creek. The old canal had been filled in so you could walk from the visitors center around the turning pond and immediately be on the towpath. Now the aqueduct has been restored. The canal was dug out so that it connects to the turning pond, fills the aqueduct, and runs maybe forty yards beyond the north end of the aqueduct. This is a great improvement. My wife shared with me that before the improvement, she couldn’t visualize what the aqueduct did, since it looked like, and was used as, a bridge. Now that it has been repaired and has water in it, its function is clear.

That small portion of the
canal connects to the
turning pond.

One more plug: I also think it’s a good place to put the park headquarters as Williamsport is (again in my humble opinion) the best place to visit the C & O if you only have a day to spend there. In Williamsport there is a turning pond, which you only find at the two ends of the path. There is a restored aqueduct with water. There is the elevated railroad bridge to see. Less than half a mile walk down the towpath is Lockhouse 44 with an excellent example of a canal lock. (If you need to know how one of these locks works, here’s a video I found that shows how one works, it’s from a canal in Great Britain, but I chose it to share with you because it looks very similar to the C & O.) And for a bonus, there is some Civil War history as well. Confederate forces crossed the Potomac here and in other locations along the canal during both campaigns in the north. Williamsport is an hour and a half drive from Washington D.C., less than an hour from Gettysburg, and only fifteen minutes from Antietam Battlefield. If you’re planning a trip in the area, consider adding this piece of history to your itinerary.
