The state's oldest prison and the intake point for men, on North State Street in Concord — midweek-only visiting by housing unit, with the Secure Psychiatric Unit on the same grounds.

Overview

The New Hampshire State Prison for Men is the anchor of the state’s small prison system: the original state prison was built in 1812, the current structure dates to 1878, and the facility that operates today took shape in large-scale 1980s renovations. It runs from medium custody through maximum, with three general-population units, two higher-custody units, and the Reception & Diagnostic (R&D) unit where newly sentenced men, probation and parole violators, and people in short-term protective custody arrive. The state lists an active capital project to plan a replacement facility.

Two separate units share the grounds: the Secure Psychiatric Unit, the state’s most secure inpatient behavioral-health facility — which holds civilly committed patients alongside people from state and county custody, under the department’s medical division — and the Residential Treatment Unit, a step-down behavioral-health unit for male prisoners.

What Makes New Hampshire State Prison for Men Different

  • Newly sentenced men enter the system here. Intake in the R&D unit runs about 30 days of screenings, and visiting during that window is limited to one visit a week after medical clearance — the sequencing is covered in Transfers.
  • General-population visiting is midweek only. The posted schedule, in force since January 2023, closes general-population visiting Friday through Monday; the warden’s memo says weekend hours would return with roughly 24 hours’ public notice if offered.
  • The SPU runs its own visiting — Tuesday 5:00-7:00 p.m. — with its own mailing address. The RTU’s two NHDOC postings conflict (a Wednesday 5:00-7:00 p.m. night on the units’ page, versus inclusion in the prison’s regular blocks on the 2023 schedule), so RTU families confirm by phone.
  • Special Housing Unit visits are non-contact and phone-scheduled through the unit’s officer-in-charge at (603) 271-1927, on a separate schedule that includes weekend slots.
  • It is the closest men’s prison to the state’s population centers — about 19 miles from Manchester and 69 from Boston by road — which matters in a system whose other men’s facility is in the North Country.

Visiting Hours and Procedures

The statewide rules above — the notarized application that goes back to the incarcerated person, the dress code, and the ID rules — apply here. The posted facility schedule assigns each housing unit’s blocks:

The unit names are internal housing designations NHDOC does not define publicly — the person inside knows which block is theirs. The posted schedule memo dates to January 2023, so a phone check before a first visit confirms the current block and that the schedule is still in force. NHDOC publishes no visitor-information line for the prison — the sidebar number is the warden’s office, from the facility’s federal audit paperwork, and the central office answers at (603) 271-5600. Short-notice changes are announced on NHDOC’s social media. A Family Connections Center operates on site, as at all three prisons; its child-focused programs and the full approval process are in Visiting in New Hampshire.

Getting There and Parking

The prison is on North State Street at the north edge of Concord, two miles from the State House.

Distances are approximate, based on map routing. NHDOC publishes no visitor parking details for the facility.

Nearby Services

Concord is the state capital, with its full range of food, gas, and lodging starting about two miles south of the prison. Concord Hospital at 250 Pleasant Street — (603) 225-2711 — runs the area’s emergency department, a Level II trauma center, about three and a half miles from the facility.
