Man-made underground passage in Liscune Lower

Liscune Lower holds an L-shaped hollow inside a ringfort, its long arm stretching seven metres east-west and its short arm six metres north-south. The passage dips a metre below the ground, narrow enough that breath sounds like a living voice. It may have hidden people, stored grain or marked a boundary forgotten by time. Whatever it served, the earth still keeps the shape of hands that cut it.
