New Jersey State House

The New Jersey State House is the capitol building of the U.S. state of New Jersey and is the third-oldest state house in continuous legislative use in the United States. Located in the state capital of Trenton, in Mercer County, it was originally built in 1792. The building accommodates both the New Jersey Legislature's Senate and General Assembly chambers, offices of the governor, lieutenant governor, and various state government departments. From August to November 1799, the federal government relocated its offices to Trenton, with the United States Department of State headquartered in the State House, following an outbreak of yellow fever in the then-capital of Philadelphia.
