In the decades following 1923 many improvements and additions were made including a new, Commissary, Segregation Unit, Chapel, Gymnasium, and Deputy Warden’s Office

In 1992 the Segregation Unit closed and a new “Super Max” facility opened in the neighboring town of Warren.

On February 11, 2002, the Maine State Prison at Thomaston closed and 400 prisoners moved to a new 900 bed, maximum security facility in Warren, Maine.

On March 21, 2002, demolition began and after 178 years the old prison became part of Maine history.
