Lockhouse 21 had a long and storied history of inhabitation by the Swains family, who owned the property for over 100 years before donating the building to the Park in 2005. The interior tells their story through scrapbooks, photographs, games, and literature. Themed to interpret the 1910s, when the Canal was still active, Lockhouse 21 offers guests the opportunity to visualize a bygone era of Montgomery County history, and provides easy access to both D.C. and its commuter cities like Germantown and Bethesda.

Lockhouse Overview

Lockhouse 21, locally known as “Swains” after the family who lived there for over a century, is the newest lockhouse to join the Canal Quarters program. Opened in July 2019, this lockhouse has been completely modernized and is ADA-accessible with a bathroom and Murphy bed on the first floor, ramps into the house, and hallways wide enough to accommodate a wheelchair.

The house interprets 1916, the year the National Park Service was formed and the date when the C&O Canal was beginning to transition from a working canal to a recreational space. Unique period furnishings transport visitors to the early twentieth century, and scrapbooks tell stories of a time when Woodrow Wilson was President, the United States had not yet entered World War I, and the women’s and civil rights movements were gathering steam.

Lockhouse 21 features accessible parking, accessible ramps to the front door and within the first floor of the building (upon request during booking), accessible bathroom, kitchen, and picnic area facilities, and single-sized Murphy bed located on the first floor. The second floor is only accessible via stairs. The lockhouse sits beside a parking lot and is not as secluded as the other lockhouses, but is the most recently rehabilitated.
