Delaware Governor's Mansion
Known as Woodburn, the Delaware Governor's Mansion has served as the official residence of the state's governor since 1965. Charles Hillyard III bought the land at a sheriff's sale for $110 in the 1780s and built the house in 1790. It was listed on the National Register of Historic Places as "Governor's House" in 1972.
