The Bishop of London has added his support for a campaign to save a chapel on the former Chelsea Barracks site.
The Right Reverend and Right Honourable Richard Chartres penned a letter to culture minister Barbara Follett, asking her to spare the 19th Century garrison church from demolition by giving listed status.
Developers Project Blue plan to remove the chapel under their £1billion plans to redevelop the former army site, which lies on the area of land between Chelsea and Pimlico bordered by Chelsea Bridge Road and Pimlico Road, to make space for a 1.3 acre public park.
In his letter, Mr Chartres wrote: "After some research I've come to accept the importance and value of this building."
He added that he would like to be associated with the case mounted by the Barracks Action Group (BAG), which wants the church to become a listed building to save it from being demolished.
BAG chairwoman Georgine Thorburn, of Bloomfield Terrace, Pimlico, said: "It's really great to have the support of the Bishop of London. The church, the only remaining garrison church in central London, is all that remains of the original Victorian barracks after they were rebuilt in 1960.
"It's now considered a memorial to our soldiers, and it would be an atrocity to see it torn down. It would benefit the community by providing a space suitable for use as a church, scout hall, cafe, concert hall, amateur theatre or to hold charity events."
A Project Blue spokesman said the chapel should go as it stands in the middle of a planned area open space. He added: "We're pleased at the welcome given to our proposal to commemorate the generations of soldiers who lived and worked at Chelsea Barracks through the use of contemporary landscape design and the installation of public works.
"Recently, we've taken soundings from senior representatives of the Guards regiments who served at Chelsea Barracks and they've been unanimous in stating that they have no sentimental attachments to the building and would be completely unconcerned if it was demolished.
"The landscaped garden, which our neighbours and Westminster Council are demanding, can only be delivered if the chapel is demolished."
