lockhouses located along the C and O
Canal Towpath trail in Maryland.
In the course of the 184.5 mile canal, there were 57 lockhouses. Of those 57 structures, 26 are still standing. Not only are they still standing, but some of them are being put to use as overnight lodging for weary canal hikers and towpath bikers.
To learn more about these incredibly functional museums/dorms/hotels, you can read the excellent article in National Parks magazine or visit the Canal Quarters website. You can also visit the Chesapeake & Ohio Canal website put together by the National Park Service.
