Superintendent’s House, 3500 Dismal Swamp Canal Trail: At the 5-mile mark along the Dismal Swamp Canal Trail sits the Superintendent’s House. It’s the only structure still standing on land once owned by the Dismal Swamp Canal Company. The structure is a 19th-century version of prefabricated housing. First constructed elsewhere, pieces of the building had Roman numerals making it easier to put back together. They were placed on a barge that floated on the canal. (Melissa A. Winn)
