Dartmoor Prison has been praised for progress made since a damning report three years ago.
Dartmoor had been described as 'the prison that time forgot'
A new report by the Chief Inspector of Prisons welcomed positive changes at the jail but said it was still struggling to get to grips with its role as a category C facility.
In 2001 the Chief Inspector of Prisons severely criticised Dartmoor describing it as a "prison living in its own past".
This latest inspection has found significant improvements.
Culture of intimidation
The report confirms Dartmoor is a visibly different prison and welcomes the changes made.
It says the jail is less oppressive, with a less "over controlled atmosphere".
The prison had been condemned for treating inmates like dangerous animals amid a culture of over-control and intimidation.
But since the last report steps have been taken to improve race relations and facilities for employment.
The prison has now reopened a workshop and will be improving training in areas such as bricklaying and carpentry.
And the prison's segregation unit with its cage and pens has been replaced by a new resettlement unit.
There is also the possibility of a new unit to deal with sex offenders.
