Aerial footage shows the stone remains of a medieval stronghold on a tree-fringed green hill, with the camera tracing the line of the old walls from above.

The shot then takes in a red-roofed manor house and its parkland at the foot of the hill; as the camera climbs, the town’s streets and distant fields stretch to the horizon.

Heritage specialists say regular maintenance and careful visitor management are key to preserving sites like this.
