Lytham Hall, which was built in 1756, is a shock new entry on the English Heritage list, which details failing historical treasures across the country.

Fylde MP Michael Jack wants the listing of the hall to act as a "wake-up call" to heritage bosses who hold the purse strings to vital cash for revamping the Grade I listed manor house.

The hall is currently leased to the Heritage Trust for the North West, a separate body, by the Lytham Town Trust, who purchased the building in 1997.

Mr Jack, who opened a new wing at the hall 12 months ago, said: "Hopefully Heritage Trust for the North West will now be given more priority for the work.

"They have done a good job up to now but more work needs to be done. The disappointment is for various reasons it is taking a long time.

"This may give a wake-up call to all concerned to finance the work for the future of the hall and the benefit of the local community. Otherwise a treasure will be lost."

The hall was built for Thomas Clifton by John Carr of Yor, between 1752 and 1764.

It has been listed as a priority 'B' property by English Heritage chiefs, which is the second most serious of six gradings used by officials.

It is described as being in "fair" condition despite being deemed to be in "immediate" risk.

Culture groups hope the listing will give a kick-start to work to secure the future of the hall.

Alan Ashton, president of Lytham Town Trust, said: "The deterioration is because improvements are being made piecemeal.

"I think funding should be given for the maintenance that is so desperately needed. Heritage Trust for the North West are having difficulty overcoming the problems. There is a great deal of history behind the hall."

Marion Coupe, chairman of the Lytham St Annes Civic Society, is pleased the plight of the hall is being brought to the public's attention.

She said: "We are also happy because it means the hall will qualify for certain grants. It is important people understand how much is costs to look after the hall."

The Shrine of Our Lady of Lourdes on Whinney Heys Road near Blackpool's Victoria Hospital, remains on this year's doomsday list.

The chapel has been redundant since 1998. English Heritage has offered more than £70,000 towards the works.
