Wilmington’s Commercial Historic District (H1 Zone) is a historic district registered on the Secretary of the Interior’s National Register of Historic Places. The district (roughly bounded by Columbus Street on the North, Sugartree Street on the South, Mulberry Street on the West, and Walnut Street on the East) is significant due to its architectural style, specifically late 19th and early 20th century revivals and the late Victorian style.
