A 19th century coastal fort, a Victorian lime works and the 14th century remains of a former hospital are among hundreds of sites across Sussex to be included in a new register aimed at saving historic treasures.

The list has been revealed as English Heritage prepares to launch its Heritage At Risk campaign next month.

Based on its annual Buildings At Risk register, which lists Grade I and Grade II* listed structures, the directory has been extended to include Grade II listed buildings.

It will also now include scheduled monuments, archaeology, historic landscapes, parks, gardens, places of worship, conservation areas, battlefields and even designated maritime wrecks.

All the sites are deemed to be at risk through decay, damage and vandalism.

Andy Brown, South East planning and development regional director, said: "It is all about getting a proper grip on what's putting the heritage at risk.

"At the top of our Buildings At Risk register at the moment is Castle Goring in Worthing. It is a wonderful building and we have been trying for a long time to get some action on preserving it.

"We will also be moving into a new area - archaeological sites such as the South Downs are crammed packed with prehistoric archaeological remains.

"We know it's got a huge amount of evidence in there. We need to find out how to prioritise the various threats it faces, whether it's from rabbits and badgers or from farming.

"The project will help us use our grant aid in a much more targeted fashion but we can also help some of the other regional players such as Natural England to prioritise their resources. It will also help us engage local communities to address what is precious to them and use the enthusiasm of volunteers in a more effective way."

Shoreham Old Fort on Shoreham Beach was on last year's buildings register.

Open to the elements and exposed to vandalism, the fort, which has also been used as a coastguard observation post, is beginning to badly deteriorate.

Maison Dieu, the ruins of the former hospital of the Holy Trinity in Mill Road, Arundel, is in two parts divided by a road, both with different owners. The register identified one part of the building as Priority A - in the most urgent need of repair.
