The most northern of Delaware’s three counties, New Castle is host to the state’s largest city, Wilmington. Founded in 1637 by the Swedes, the Dutch soon laid claim to the region and then had to turn the area along the Delaware River over to the British as recompense, although they did that reluctantly. The Duke of York in 1673, transferred the name of New Amstel to New Castle. Not an entirely original name, but the Duke hath spoken. While the only castle in the county was a defunct White Castle in Wilmington, a delineation of a stone version sits atop the county seal, which holds the center of this iron cover from East Jordan foundry. A boat wheel and clipper ship flank the bordered text referencing the nautical nature of the county’s heritage. These are surrounded by standard descriptive texts and multiple pick points. A curiously shaped gum splat floats near the word “SEWER.” One can find this cover all over the county, including the historic town of New Castle.
