About Altarnun, Cornwall

Altarnun reveals itself through the grey, enduring granite of its church, a structure often called the Cathedral of the Moors. It lies 7.0 miles west-south-west of Launceston (from Launceston: bearing 252°T, OS grid SX 223 812), and is situated north-north-west of Fivelanes village. The light here pulls long, silver shadows across the ancient stones of the medieval wayside cross standing silently in the churchyard. Beyond the church, the land rises toward the rugged, wind-brushed heights of Trekennick Tor, where the air tastes of salt and distant gorse. Further south, the dampened, quiet expanse of Trewint Marsh holds the winter rains, mirroring the shifting moods of a vast Cornish sky. Altarnun remains a place where the weight of centuries presses into the bedrock, marked by the steady, unpretentious endurance of those who walk its lanes. The water of the nearby streams cuts through the landscape with a persistent, rhythmic clarity that has shaped the valley for ages. Time seems to gather in the hollows here, lingering long after the sun has slipped behind the western hills.
