The lock house at Lock 25 along the C&O Canal in Edwards Ferry, Md. (Chris Hanessian)

Consider spending a night in an antebellum lock house in Edwards Ferry, Md., next to the scenic Chesapeake and Ohio Canal. There is space to sleep eight in the tiny brick house, furnished as it would have been during the Civil War.

You could call it living the simple life. There is no heat, no running water, no electricity and no kitchen in the 1830-era house. There is an outdoor fire ring for cooking as well as an outdoor portable toilet. Just one-third of a mile away is a water supply.

During the war, the family who lived there tended Lock 25 to allow boats to pass through on their way to Washington or as far north as Cumberland. The lock tenders got a rent-free house in exchange for being on duty round-the-clock. Usually the cargo in the passing boats was coal, but it could also be soldiers. The families living along the canal would witness the beginning and the end of several Confederate campaigns into Maryland. They would also find Union soldiers assigned to guard the canal, camping on their land and helping themselves to the family’s garden.

As a house guest, there is no lock duty and no Confederate or Union raid is expected. Your host is the C&O Canal Trust, the official nonprofit partner of the Chesapeake & Ohio Canal National Historical Park.

The charge is $100 per night with a limit of three nights. The renter brings linens and any food or drink. The honor system calls for departing guests to take with them every single thing they brought to the lock house.
