A recently updated list of the world’s 100 most endangered archaeological sites includes the former Battersea power station in London and 18th century Strawberry Hill, also in London, former home of commentator, historian and collector, Horace Walpole.

Of the power station, the World Monuments Fund (WMF) said it had become an indelible part of London’s skyline but – after being abandoned since its decommissioning in 1983 – is now derelict and in danger of decay.

One proposal for its regeneration involved the conversion of the building into a mixed-use leisure centre, but this has so far come to nothing. A local community group is campaigning for stabilisation measures and staged rehabilitation work to begin as soon as possible whilst the site’s long term future is considered.

Strawberry Hill’s interior is said to be in need of urgent repair, as are its Renaissance enamelled-glass windows, one of the finest collections in the world. The building has most recently been used as a teacher training college but the owners cannot afford the cost of the necessary restoration. Negotiations are currently in hand to transfer the ownership of the property to the Strawberry Hill Preservation Trust, permitting funds to be raised solely for its conservation.

Other new additions to the list, which is updated every two years, include a hut built by Sir Ernest Shackleton at Cape Royds in Antarctica in 1908, a rock art complex on Australia’s Dampier Archipelago, the entire former steam-powered railway system of Paraguay and Perm-36 in the Ural Mountains, Russia’s only surviving intact gulag camp.

This is the first time that the WMF has identified endangered structures on every continent. Details: www.wmf.org
