Slight univallate hillfort with outworks containing a medieval chapel and beacon at Helsbury Castle

Helsbury Castle is a slight univallate hillfort with outworks containing a medieval chapel and beacon at Helsbury Castle in Cornwall, England, where ancient defences still circle a place that later became a landmark for light and faith. The hill may have watched coast traffic for centuries, its ridge marked by a beacon whose flame answered distance and danger. A chapel within the fort suggests people still gathered there long after battle ceased, perhaps trusting the old boundary more than any new wall.
