Woodburn, on King's Highway, is the official residence of the Governor of Delaware and one of the finest examples of Georgian architecture in the state. Built around 1790, the house is open for public tours on Saturdays from spring through autumn. The rooms are furnished with period antiques and Delaware-made objects, and the guides explain both the architectural history and the building's long role in state politics.
The house sits within a garden that contains trees thought to be among the oldest in Delaware. The grounds are also worth visiting — the old mulberry tree in particular is believed to date from the colonial period. Woodburn is one of the stops on the First State Heritage Park trail and can be combined with visits to The Green and the Old State House.
