Four Locks

Four Locks is a former small community which is now part of the Chesapeake and Ohio Canal National Historical Park. It was once a thriving community of homes and businesses in Washington County, Maryland that supported the Chesapeake and Ohio Canal from the mid-19th century, until its closure in the 1920s. In its heyday, the small community consisted of two stores, two warehouses, a dry dock for boat repair, a school, and post office, plus about a dozen houses.
