🔒 Burlington County Prison

The Burlington County Prison is a historic museum property, located at 128 High Street in Mount Holly in Burlington County, New Jersey, United States. Operating from 1811 to 1965, it was the oldest operating prison in the nation at the time of its closure. Designed by Robert Mills, its design exemplified period thinking in progressive prison design, with individual cells, good ventilation, and fireproof construction. It was documented by the Historic American Buildings Survey (HABS) in 1937. Now operated by a local nonprofit as a museum, it was designated a National Historic Landmark in 1986. It was later listed as a contributing property of the Mount Holly Historic District on February 20, 1973.
