In the middle of Tintagel village, among the shops and the summer crowds, stands a long, low building of rough grey slate, and the first thing you notice is its roof. It ripples. It sags and swells in gentle waves, as though the whole house had softened and slumped a little over the centuries. This is the Old Post Office, and despite its name it is one of the oldest and most charming small buildings on the entire Coast Path.
Begin with the name, because it misleads. This is not, and never really was, a post office. It was built in the fourteenth century as a small manor house, the home of a yeoman farmer, a solid stone dwelling laid out in the medieval fashion with a central hall open to the rafters. For most of its long life it was simply a house.
Only in the eighteen-forties and fifties did one room briefly serve as the district letter-receiving office, the place where the parish came to send and collect its post. That handful of decades gave the building its name, and the name stuck for good. By the end of the nineteenth century the old house had fallen into decay and might easily have been lost.
It was saved by a campaign led by an artist who loved it, and in 1903 it became one of the very first buildings ever taken into the care of the newly founded National Trust. It has been protected ever since.
Step up to it, and look for the details that make it special. First, that roof. Built of heavy local slate on timbers that have bowed and settled over six centuries, it undulates in slow waves against the sky, and it is the single most photographed thing here; shoot it with the clouds behind and you will see why.
Second, the walls, rough-coursed slate-stone quarried from this very coast, thick and irregular, the true building material of north Cornwall. Third, step inside to the medieval hall, small, dim and human-scaled, a rare survival of how ordinary well-off people actually lived in the fourteenth century, when most such houses have long since vanished.
Fourth, find the recreated Victorian post room, fitted out as it would have looked in its brief life as the parish letter office, a little window into the eighteen-fifties. Fifth, look for the cottage garden in front, planted in traditional style, loud with bees and butterflies in summer and a soft foreground to the grey stone.
Here is what makes this humble house quietly moving. For six hundred years it did nothing famous. It sheltered farming families through good harvests and bad, watched generations born and buried, and slowly, gently, let its roof sink under the weight of its own slates.
It survived not because it was grand but because, at the very moment it might have crumbled away, people decided that ordinary old things are worth keeping. The artist who fought to save it, and the young National Trust that took it on in 1903, were making a then-radical argument: that a modest medieval farmhouse mattered as much as any castle. Standing before that wavy roof, you are looking at one of the small victories that began the whole idea of saving the ordinary past.
From the door of the Old Post Office the Coast Path awaits, climbing back out of the village to run steep and exposed along the slate cliffs toward Port Isaac. Just up the road stand the wind-blown ruins of Tintagel Castle and its legends of Arthur, all thunder and drama.
But pause here first, in the quiet, and take one long look at this gentle, undulating little house that has outlasted six centuries simply by being loved. Then shoulder your pack for the cliffs. Walk safe.
