HM Prison Pentridge was an Australian prison built in 1850 in Coburg, Victoria. The first prisoners arrived in 1851. The prison was closed on 1 May 1997.

Pentridge was often known by the nicknames "The Bluestone College", "Coburg College" or the "College of Knowledge". The grounds were originally landscaped by renowned landscape gardener Hugh Linaker. Since closing, much of the prison has been pulled down to make way for a housing development. Large buildings have been built and a 16 floor modern apartment block is being planned.

The northern section of the prison being developed by Valad Property Group and the other areas by Pentridge Village. The National Trust does not like the development plans approved by Heritage Victoria. These plans include taking down sections of the outside walls and building apartments between the historic prison buildings.

Divisions 
The prison was split into many divisions, named using letters of the alphabet.

 A - Short and long-term prisoners of good behavior
 B - Long-term prisoners with behavior problems
 C - Vagabonds and short term prisoners, where Ned Kelly was imprisoned (Demolished in 1976)
 D - Remand prisoners waitng for trial
 E - A dormitory division housing short term prisoners
 F - Remand and short-term
 G - Mental health problems
 H - High security, discipline and protection
 J - Young Offenders Group- Later for long-term with record of good behavior
 Jika Jika - maximum security risk and for protection, later renamed K Division

Jika Jika high security unit 
Jika Jika, opened in 1980 at a cost of AU$7 million. It was a 'gaol within a gaol', designed to hold Victoria's toughest and longest serving prisoners. It was awarded the 'Excellence in Concrete Award' by the Concrete Institute of Australia. It was closed after the deaths of five prisoners in 1987.

Jika Jika had six separate units each at the end of radiating spines. It had electronic doors, closed-circuit television and remote locking. This meant it could use less staff but still have maximum security. The furnishings were sparse and prisoners exercised in escape proof yards.

In 1983 four prisoners escaped from ‘escape proof’ Jika Jika. When two prison officers were disciplined in relation to the Jika Jika escape a week-long strike occurred.

1987 Jika Jika prison fire 
Inmates Robert Wright, Jimmy Loughnan, Arthur Gallagher, David McGauley and Ricky Morris - from one side of the unit - and Craig 'Slim' Minogue and three other inmates on the other side sealed off their section doors with a tennis net. Mattresses and other bedding were then stacked against the doors and set on fire. They covered windows in the day room with paper so the prison officers could not see which prisoners caused the damage.

Prisoners Robert Wright, Jimmy Loughnan, Arthur Gallagher, David McGauley and Ricky Morris died in the fire. Convicted Russell Street bomber Craig Minogue and three other inmates survived as they were evacuated when the fire started.

Grave sites 

The graves of executed prisoners were unmarked in a corner of the prison. In 1929, 32 bodies were moved from the Melbourne Gaol during the building of the Royal Melbourne Institute of Technology. These graves were found in 2008. The skeleton of bushranger Ned Kelly was among those discovered.

Executions
There were 11 executions at Pentridge. The gallows beam and the trapdoor were moved from the Melbourne Gaol and put into "D" Division in 1924.

When the gaol was closed, the beam and the trapdoor were taken back to the Melbourne Gaol to be part of its historical display.

Last execution
Ronald Ryan was the last man executed at Pentridge Prison and in Australia. Ryan was hanged in "D" Division at 8.00 on 3 February 1967. He had been convicted of murdering a prison officer during an escape from the same prison. Later that day, Ryan's body was buried in an unmarked grave within the "D" Division. There is still debate about his hanging.
