Dry stone wall using stones quarried at Knowles Quarry.

Devon has more hedgerow than any other English county – around 33,000 miles of it. Many of these are “Devon hedges”: earth banks faced with stone or turf, some dating back over 800 years to Saxon estate boundaries. Traditional Devon hedges and walls are most commonly faced with granite, but locally quarried volcanic trap stone – the same material used in Exeter’s Roman city walls, the Exe Bridge and the Cathedral – is prevalent in East of Dartmoor.
