Kentucky's oldest prison and its only maximum-security facility, in Eddyville; a prison for men that holds the state's men's death row and the execution chamber.

Overview

Kentucky State Penitentiary (KSP), known as the “Castle on the Cumberland,” is a maximum-security state prison for men in Eddyville, Lyon County, in western Kentucky. It is operated by the Kentucky Department of Corrections (KY DOC). Opened in the 1880s, it is the oldest prison in the state system and the Department’s only maximum-security facility.

KSP holds men classified to maximum custody, including a higher-custody restrictive-housing population and men under a death sentence. Because custody assignments and housing change, the prison listed on the Kentucky Offender Online Lookup may differ from where a person was previously held; check the locator to confirm the current facility before planning a visit.

What Makes the Kentucky State Penitentiary Different

  • It is Kentucky’s oldest prison, in operation in Eddyville since the 1880s, and is known as the “Castle on the Cumberland.”
  • It is the state’s only maximum-security prison, holding the highest-custody male population, including higher-custody and restrictive-housing units.
  • It holds the men’s death row and the state execution chamber. Kentucky retains the death penalty in law, but executions have been under a court-ordered hold since 2009, and the most recent execution in the state was in 2008. Women under a death sentence are held separately, at the Kentucky Correctional Institution for Women in Pewee Valley.

Getting There and Parking

Kentucky State Penitentiary is at 266 Water Street, Eddyville, KY 42038, in Lyon County, in western Kentucky. Eddyville is near Interstate 24 between Paducah and Hopkinsville, roughly two hours northwest of Nashville, Tennessee. Confirm visiting days, the schedule, and the person’s custody and visitation status before making the trip.

Nearby Services

Eddyville and the neighboring Kuttawa and Lake Barkley area offer lodging, fuel, and restaurants, with additional options in Princeton and Paducah to the west. Hospital emergency services are available in the surrounding region.

Mail

Incoming personal mail goes directly to the institution, addressed to the person by their committed name and Kentucky DOC inmate number, followed by the facility’s mailing address (266 Water Street / P.O. Box 5128, Eddyville, KY 42038). Mail is opened and inspected for contraband before delivery; under Kentucky Corrections policy, correspondence is delivered to the person within 48 hours of receipt on normal workdays.

Legal and other privileged mail — from a licensed attorney, a court, a government official, the Department of Public Advocacy, or Corrections officials — is opened only in the person’s presence and should be clearly marked as legal mail.

Books and magazines must be shipped new, directly from a publisher or an approved retailer; items sent by individuals are refused. Packages are limited to approved-vendor care packages arranged through the facility.

Verify the exact mailing address, current mail rules, and approved package vendor with the facility before sending anything, because procedures change.
