When children go home to tell mum and dad what they did at school few can claim to have been tracking down First World War fortifications.

But that was what pupils of Northrepps Primary, near Cromer, were able to boast after undertaking a trail of military pillboxes.

They were rewarded this week for becoming the first school to successfully complete the trail, which forms part of north Norfolk's First World War centenary commemorations.

Framed certificates were presented to members of Oak Class by North Norfolk District Council leader Tom FitzPatrick and chairman Annie Claussen-Reynolds.

Children decided to tackle the trail after studying the conflict as part of a school topic. Teacher Kathryn Leigh, who led the trip, said: 'We are very much committed to outdoor learning and the trail helped bring history to life. They are the first children to complete the trail so are all very proud.'

The gun emplacements were mounted along the Norfolk coast during the First World War to repel a feared German invasion.
