The Maine State Prison stood in Thomaston from 1824 until it was razed in 2002. The original building was a wood structure for the guards and warden; the cells were exposed to the elements and below ground level. Prisoners were literally lowered into their deep cells at night and the opening was covered with a heavy grate to keep the men in place until they were allowed out to work in the quarry the following day. Wooden barracks with cells eventually replaced this deplorable housing. In 1923, a fire led to the construction of a third building, this one made of brick. By the turn of the twenty-first century the building was quite antiquated. A new facility was built in the neighboring town of Warren. The prisoners were moved there in February 2002 and the prison was demolished in April of that year.
