Delaware Trust Building, now known as The Residences at Rodney Square, is a historic office building and bank headquarters located at Wilmington, New Castle County, Delaware. It was built in 1921, as a 13-story, 15 bay by 15 bay, "U"-shaped steel frame building in the Classical Revival style. The building has a watertable of gray granite, a limestone-clad two-story plus mezzanine base, and a shaft of buff colored brick. Atop the building is a limestone cornice. The Market Street elevation features three monumental-scaled arched entrance openings reminiscent of ancient Roman buildings. It once had a 22-story modern office building at its center that has since been removed. The building has been converted to residential use.
