A coastal landmark which has towered over the countryside for more than 200 years has been cordoned off for safety reasons as repairs begin. 

There are serious concerns over the condition of Burnham Overy Staithe Windmill, between Brancaster and Wells.

The National Trust, which owns the Grade II listed tower mill, says its fanstage platform could collapse in high winds and an "emergency removal" of the structure is now under way.

Once the platform has been removed, the next phase of work will be focused on making the cap water-tight and improving the ventilation throughout the windmill.

"These measures, together with repairs to the roof covering of the extension part of the building to the side of the windmill tower, are intended to alleviate problems associated with water ingress and damp in the building," added the NT.

Once repairs are completed, the NT said it would decide how the mill, which was formerly a holiday let, might be used in the future.

"We are exploring all options in order to make the conservation and repair of the windmill financially viable," it said.

MILL'S TWO CENTURIES OF HISTORY 

The six-story tower mill was built to harness the power of coastal winds in 1816.

It ground corn for a century until it was sold in 1926 to Cambridgeshire architect Hugh Hughes, who converted it into a holiday home.

In 1957, the mill was restored with a new cap, platform and sails.

The building was given to the NT in 1958. In 1978, the trust published plans to restore the mill to working order.

But the proposals, which included converting part of it into a shop and adding a car park, were turned down after the county council said the roads around it could not cope with an influx of visitors.

New sails were fitted in 1985. In recent years, the building has been used as a holiday let.
