Sperrin Mountains

They're in a fairly inaccessible location in the Sperrin Mountains, about an hours climb for firefighters, burdened with equipment.

On 6 August 1945, the same day the US dropped a nuclear bomb on Hiroshima, an English soldier lost his life in a plane crash on the Sperrin mountains.

The Beaghmore Stone Circles are located at the foot of the Sperrin mountains - one of the few areas in Northern Ireland unaffected by light pollution.

The seven mystical circles and 10 rows of stones are nestled amid the green grass and heather-clad moorland of the Sperrin Mountains.

The Sperrin mountains currently play host to a number of giant troll sculptures made by the Danish artist Thomas Dambo.
