A maximum-security men's prison in Portage, in central Wisconsin.

Overview

Columbia Correctional Institution (CCI) is a maximum-security men’s prison in Portage, in Columbia County, central Wisconsin. The institution opened in 1986 and sits on a 110-acre site. According to WI DOC, it operates ten maximum-security units of 50 cells each, plus one minimum-security unit with 150 beds, for a total capacity of about 650. It is one of Wisconsin’s maximum-security institutions for men, run by the Department of Corrections’ Division of Adult Institutions.

Wisconsin abolished the death penalty in 1853 — the first U.S. state to do so — so there is no death row and no execution chamber at any Wisconsin prison.

What Makes Columbia Different

  • It is a maximum-security men’s prison, one of several maximum-security institutions in the Wisconsin system.
  • It also operates a minimum-security unit (150 beds) alongside its ten maximum-security units, so custody levels on the grounds differ.
  • It is in central Wisconsin near Portage, off the Interstate 39/90/94 corridor, which makes it reachable from Madison and points north and south.

Mail

Incoming personal mail does not go to the prison. Wisconsin sends personal mail to an off-site vendor, TextBehind, which opens and photocopies it and forwards copies to the institution; people with tablets may also receive electronic photos. Address personal mail with the person’s full name, DOC number, and the full (unabbreviated) facility name to: TextBehind, P.O. Box 189, Phoenix, MD 21131. Legal and privileged mail is exempt and goes directly to the institution at its own legal-mail address. Books and other publications must come from an approved vendor, shipped directly from the retailer, not from individuals. Full rules are in Mail & Packages.
