Wilmington Hundred

Wilmington Hundred is an unincorporated subdivision of New Castle County, Delaware.

Hundreds were once used as a basis for representation in the Delaware General Assembly, and while their names still appear on all real estate transactions, they presently have no meaningful use or purpose except as a geographical point of reference.

Wilmington Hundred is that portion of New Castle County that surrounds the confluence of the Christiana River, and Brandywine Creek, where they enter the Delaware River, and is one and the same as the municipal corporation of the city of Wilmington.

It is in the Piedmont and Atlantic Coastal Plain regions with several low hills overlooking the Delaware River.

A portion of the Philadelphia, Wilmington and Baltimore Railroad, subsequently the main north–south line of the Pennsylvania Railroad, now Amtrak's Northeast Corridor, and a portion of the old Baltimore and Ohio Railroad, now CSX Transportation's Philadelphia Subdivision, both cross through Wilmington.
