Robert Mills was 29 years old when he designed the Burlington County Prison, completed in 1811 on High Street in Mount Holly, New Jersey. Mills had trained under Benjamin Latrobe, one of the principal architects of the U.S. Capitol, and would go on to design the Washington Monument. The Burlington County commission gave him an early opportunity to apply progressive thinking about incarceration.
The design reflected contemporary reformist philosophy: individual cells rather than mass dormitories, good ventilation, fireproof masonry construction, and a clear separation of prisoner categories. The motto inscribed over the entrance read: Justice Which, While it Punishes, Would Endeavor to Reform the Offender. The U-shaped ashlar masonry structure included wall-mounted shackles in the maximum-security top-floor cell — the philosophical aspirations of the design coexisting with its harsher realities.
The prison operated from 1811 to 1965 — 154 years. Public hangings took place in the prison yard under early New Jersey law, which required capital punishment to be carried out in the county of conviction. Joel Clough, convicted of murder and hanged in 1833, is among the most frequently documented of those executed on the grounds.
When the prison closed in 1965, it held the distinction of being the oldest continuously operating prison in the United States. County officials considered demolishing it. A local preservation movement succeeded in converting it to a museum by 1966. The National Park Service designated it a National Historic Landmark in 1986.
The museum is currently managed by a nonprofit organization and is open Thursday through Sunday, offering self-guided tours, an audio tour in English and Spanish, spirit box rentals, an escape game, and October ghost tours.

Joel Clough was hanged at Burlington County Prison in 1833 after his conviction for murder. The Death Cell where he was confined before his execution on the ground floor has become the focal point of the prison's paranormal record. Investigators regularly report consistent electromagnetic field anomalies in that cell, distinguishable from readings taken in adjacent spaces.
In addition to the Death Cell, the third floor has accumulated a high concentration of reported phenomena over years of investigation. A uniformed male figure has been reported in the basement by visitors and investigators alike.
Multiple paranormal investigation groups have conducted formal studies at Burlington County Prison, producing audio recordings they describe as containing voices, film capturing anomalous light formations, and electromagnetic field spikes in the Death Cell and third-floor spaces. The museum acknowledges the prison's haunted reputation and actively programs around it — October ghost tours are offered annually.
The prison's 154-year operating history, its public execution record, and the physical character of the building — stone-walled, dim, with original hardware intact in many cells — create conditions that paranormal investigators describe as favorable to sustained activity.
The museum offers spirit box rentals for visitors who want to conduct their own informal investigations during self-guided tours, a practice that reflects the venue's acknowledgment of its dual identity as historic institution and paranormal destination.
