The original 1732 court is built over the remains of the 1660s courthouse, with additions and modifications throughout the 18th and 19th centuries. All jurisdictions of Delaware's courts, and including the federal courts, have met in this building. The state courts removed to the City of Wilmington in 1881 with the changing of the county seat, but occasional court sessions and proceedings are still held here.
