McNeil Island Corrections Center

McNeil Island Corrections Center was a prison facility spanning multiple buildings on an isolated island in Puget Sound, reachable only by authorized ferry. The complex held incarcerated people and housed a residential community for staff members and their families on the island.

Operations began in 1875 as a territorial jail before Washington became a state, eventually developing into a federal penitentiary for over a century. It remained the last operating island-based prison facility in the country until its closure in 2011.

Staff members and their families formed a complete community on the island, creating their own social structures and daily routines separate from the outside world. This close-knit settlement shaped how people lived and worked together in this remote location.

The facility was not open to the public due to its isolated island location and restricted access that required authorized ferry service. Visiting required special permission and security clearance from prison authorities.

The prison held several high-profile inmates including Charles Manson, Alvin Karpis, and Robert Stroud at different times during its operation. These well-known prisoners brought wider attention to the remote facility.
