A bunker built to house Scottish Office staff in the event of a nuclear attack has been bought by a technology firm. The bunker at Cultybraggan Camp, near Comrie, has been sold to online service company Bogons Ltd for £150,000.

Built at the end of the Cold War but never used, the bunker was bought along with the wider camp by the Comrie Development Trust in 2007. The money raised in the sale will go towards paying off loans taken out to purchase the camp.

The bunker is thought to be the last of its kind built in Britain, having been completed in 1990 at a cost of £30m. It would have served as a national command centre in the event of a nuclear attack, and is equipped with a radio mast, TV studio, telephone exchange, decontamination showers and dormitories.

After being closed down almost immediately following the end of the Cold War, the bunker was marketed as a good location for data storage, as it is shielded from solar flares which can affect computer equipment.

New owner Brandon Butterworth said he was "pleased" to have bought the bunker.
