Four Locks - locks 47 through 50 - were built between 1836 and 1838, all within a half-mile stretch of the canal. Nestled amongst these four locks, a close-knit community thrived while the canal was in operation. Businesses prospered, meeting the needs of locals and boatmen.

In its heyday the busy town of Four Locks included two general stores, two warehouses, a dry dock, mule barn, post office, school, farms, and many houses. Families like the Hassetts, the Myers, and the Flynns worked and lived together here, and called this place home.

After the canal closed in 1924, the community declined and has all but disappeared. The legacy of Four Locks stands in the buildings seen today and lives in the memories of a community long gone.
