A manor house with intimate links to Britain's nuclear history and a Devon pavilion that was frequented by Agatha Christie are among the most at risk Victorian buildings in Britain, campaigners revealed today.

The historic Aldermaston Court in Berkshire was once home to Britain's first commercial nuclear reactor, which was opened by Prince Philip in 1959.

But the property, which is just a stone's throw from the Ministry of Defence's secretive Atomic Weapons Establishment, has been derelict for more than a decade and is increasingly under threat, the Victorian Society said.

Aldermaston features along with the art nouveau Torquay Pavilion on the preservation group's annual top ten list of endangered buildings.

Torquay Pavilion was a favourite of Agatha Christie, Britain's most celebrated crime novelist.
