Located in the heart of Trenton, the New Jersey State House is history come alive. Our State House is the second oldest still in use. (Maryland has the oldest.) For more than 200 years, New Jersey Senators, Assemblymen, and Governors have been making the laws of the state in this building. In 1999, the restoration of the State House dome was completed. The project began in October, 1996. The dome is covered with 48,000 pieces of gold leaf. Each piece of gold leaf cost $1.00 and was paid for with money raised by New Jersey school kids through the "Dimes for the Dome" program. As a thank you for their contributions, the dome stands in honor of New Jersey children. The State House is open for tours on Saturday, February 16, 2019, hourly from 12:00 pm to 3:00 pm. The entrance is the State House Annex at 145 West State Street. Call the Tour Office for more information, 609-847-3150.
