A controversial plan to tear down part of a 115-year-old jail tonight for commercial development has drawn fierce criticism from heritage enthusiasts.

Critics say Pudu jail, which sits on prime land in the heart of Kuala Lumpur, should be preserved because of its heritage and tourism value.

Late today, a huge segment of the 394-metre (431-yard) wall surrounding the Victorian-era jail will be torn down to make way for road expansion.

NONEDuring World War II Japanese occupation forces used the jail to hold Allied prisoners-of-war, many of whom were tortured and executed there, but the government has said Pudu does not qualify for heritage status.

"The government has studied the matter and decided that the site is not a heritage site and will not be made a heritage site," Deputy Finance Minister Awang Adek Hussin told lawmakers today.

"The government is of the opinion that it is not something we can be proud of, there may be many (other) things we can be proud of compared with a jail," Awang added.

He said government-linked property group UDA Holdings will develop the site, with hotels and apartments to be built over a 10-year period beginning 2011.

Historians are angry, saying at least part of the jail should be preserved.

"There are many other places in Kuala Lumpur that can be redeveloped for commercial and residential purposes but there is only one historic prison with such significance," Singapore-based military historian Brian Farrell told AFP.

NONEMalaysian heritage board chairman Ahmad Sarji told AFP some semblance of the prison should remain even if the rest of the building was to be torn down.

"The prison has heritage significance so at least preserve the facade of the entrance, which can dovetail with whatever is being built there," he said.

Former Australian prisoner-of-war Charles Edwards told AFP in 2008 that Pudu jail should be preserved.

Edwards was a private in the Australian 8th Division, part of Commonwealth forces that defended Malaya, as it was then known, at the outset of the 1939-1945 war.

He was captured by the Japanese and endured torture and deprivation while being held at Pudu along with thousands of other prisoners-of-war.

After the war Pudu continued to be used as a prison and in July 1986 Briton Kevin Barlow and Australian Brian Chambers were hanged there, the first Westerners to be executed under Malaysia's anti-narcotics laws.

Pudu, built in 1895, was closed in 1996 to make way for a prison museum which shut in 2005. It was then used as a holding centre for prisoners undergoing trial before closing in 2008.
