The New Jersey State House on West State Street is a working legislature — the Senate and General Assembly still meet here — which makes free public tours more interesting than the average historic building. Guided tours run on weekdays and take in the legislative chambers, the governor's reception rooms, and the portrait collection.
The exterior dome is visible from much of central Trenton. The surrounding blocks include the State Museum and the Old Barracks, making this the natural starting point for a day of sightseeing.
