Dry-stone Markings
In the UK and Switzerland, it is possible to find dry stone constructions without any obvious function. The largest and oldest of them, such as Stonehenge, are likely related to ancient pagan rituals. However, the smaller structures may be built just as signs, marking the mountain paths or boundaries of owned land. (Some stand on the boundary between Italy and Switzerland; see photo). In many countries, cairns are used as road and mountain top markers.
