Petty’s Run archaeological site at Capitol Complex
now open to the public
DEP Commissioner Bob Martin, along with officials from Mercer County, the Department of Treasury, the State Capitol Joint Management Commission and Legislative District 15 unveiled the Petty’s Run interpretive archaeological site on May 14. The site, located between the State House and the Old Barracks Museum in Trenton, was one of five places in 1750s America where steel was fabricated. It continued to be a vital industrial site well into the 19th century. Six interpretive panels and a walkway around the site offer visitors a window into these layers of history. The project to preserve and restore Petty’s Run was jointly funded by the state and county.
