Massachusetts Correctional Institution - Cedar Junction

The Massachusetts Correctional Institution Cedar Junction (formerly known as MCI-Walpole) is a maximum-security prison, reception and diagnostic center that is located in Walpole, Massachusetts. It houses approximately 800 adult male inmates, including the Departmental Disciplinary Unit for the most serious discipline issues, and the reception and diagnostic center that receives all male inmates into the DOC system.

During the 1970s, this facility was one of the most violent prisons in the United States. In 1973, after the Attica prison massacre, the inmates at Walpole formed a prisoners union to protect themselves from the guards, end behavior modification programs, and advocate for prisoners’ rights to healthcare, visitation with loved ones, work assignments, and the ability to send money to their families.

The union also ended the race-related violence in the prison by creating a truce. During Kwanzaa, the black prisoners were put in lockdown which angered the other inmates and led to a strike. For three months, inmates refused to work or leave their cells, which led to the guards beating inmates, putting them in solitary confinement, and denying them food and medical care.

Eventually, the strike ended when the superintendent resigned and the inmates were granted work programs and visitation rights.

Visitors/inmates will not be allowed to enter inside the facility or exit the Pedestrian

Trap/Visiting Room area between the hours of 2:30 p.m. and 3:15 p.m., and between

4:00 p.m. and 5:00 p.m. due to operational mandates.

Inmates are allowed a maximum number of three visiting periods a week during

The maximum number of visitors allowed per visit is four. However, only two of the

Before you visit, make sure your loved one has added you to their pre-approved visiting list. It is the inmate’s responsibility to notify Massachusetts Correctional Institution Cedar Junction staff as to whom may visit. Inmates at Massachusetts Correctional Institution Cedar Junction are allowed up to ten visitors on their list.

  • Fill out a Visitor Application Form. Once completed, please mail this form to the facility at the address below. The Visitor Application will be processed, and you and the inmate will be notified of approval or denial.

Visitors must secure all personal belongings in their vehicles. Visitors without vehicles are provided with lockers. All visitors are subject to search.

The facility uses passive drug detecting dogs as part of the entrance procedures. They are used at random intervals to help detect the presence of illegal drugs entering the facility. These measures help to decrease violence within the facility and have a positive impact on staff and inmate safety overall. Everyone is subject to a drug detection dog search to include visitors, volunteers, correctional staff, contractors, etc.

These dogs, generally Golden Retrievers or Labrador Retrievers, are used because of their inherently gentle natures. They are always on a leash and handled by trained personnel, who will walk them past the line of visitors. They have been carefully trained to detect the presence of drugs by smell and to alert their handlers to that detection by sitting down.

Visitors are allowed to enter the visiting room with the following items, but must declare them to the processing officer:

  • Money for vending machines, up to ten dollars per visitor
  • Medication – Visitors who require life-saving medication on their person, must obtain prior written approval from the Superintendent to visit with such medication.
