New Jersey State House

The New Jersey State House is the state capitol building in Trenton, New Jersey, with origins dating to 1792; it is noted for being one of the oldest state capitols in continuous legislative use in the United States.

The complex contains the legislative chambers for the New Jersey Legislature - the Senate and the General Assembly - plus offices and meeting rooms used by lawmakers and state officials. Public galleries overlook the chambers and the grounds include memorials and ceremonial approaches. The site is primarily visited for its historic architecture, legislative sessions, and civic functions.

Construction began in the late 18th century and the building has been enlarged and altered several times over the 19th and 20th centuries to add office space, an annex, and modern utilities. It has continuously housed the state legislature and related executive offices since its original construction.

The State House sits in downtown Trenton, Mercer County, adjacent to other state government buildings. Trenton lies roughly midway between New York City and Philadelphia and serves as New Jersey’s capital city.
