Over a dozen commercial buildings in Seaford are listed on the National Register of Historic Places. All of these buildings demonstrate examples of late nineteenth- and early twentieth- century architecture. The views along High St. demonstrate both historic and scenic quality; historic because of their significance in telling the story of nineteenth-century Seaford, and scenic because the wide variety of building types offers varied and interesting views. Seaford’s location on the northern bank of the Nanticoke River made it a prime location for travel and trade in the nineteenth century. Oyster packing, one of Seaford’s most important industries, flourished by virtue of the water route from the Chesapeake oyster beds and the railroad, which allowed for fast delivery to northern markets. The small-town atmosphere and historic character are communicated by the historic main street with Victorian architecture and a small scale that allows residents to walk to many parts of town.
