English Heritage has released its Buildings At Risk Register 2007. The Abbey Mills Pumping Station in Newham, east London, is among the new additions to this year's list.
The register details endangered buildings which need public funding to safeguard their future. The former Ditherington flax mill in Shrewsbury has also been added to the list for 2007.
Many buildings are worth less than their restoration would cost. Restoring Chatterley Whitfield Colliery in Stoke-on-Trent would leave a £25m deficit, according to English Heritage.
Cardington Number One shed in Bedford is the oldest existing airship hangar in Europe. It dates from World War I and has also been added to the Buildings at Risk Register during 2007.
This mausoleum in Ryedale, North Yorkshire, along with its bastion wall, gates and railings, is another structure English Heritage considers at risk.
Birnbeck Pier in Weston-super-Mare has been added to the Buildings at Risk Register this year. English Heritage said some featured structures were "falling apart before our eyes".
The Crossness Pumping Station in Bexley, south-east London, features some very ornate detail inside and is another building English Heritage says needs multi-million pound investment.
The remains of the medieval Quar Abbey, near the north coast of the Isle of Wight, sit in the grounds of a monastery which is still functioning.
The imposing Royal Insurance Building in Liverpool is also a new addition to English Heritage's register of threatened buildings, which is updated annually.

The Wicker Arch and adjoining viaduct in Sheffield are on the 2007 register, which lists 1,235 threatened buildings across England that experts say need a total subsidy of £400m.
