Petroglyphs at Stykket (Stadsbygd) consists of five characters. Four depicting moose. The fifth species can not be determined. The greatest figure consists only of a head and two legs and has hardly ever been made complete. One of the animals have back bent head, which is very rare.
The figures are carved into the rock using simple stone tools sometime in early Neolithic, probably 5000 - 5500 years ago. They were made at a time when people in Norway yet lived by fishing and hunting besides gathering of shells, plants and roots.
It is unclear why the carvings were made, but they have probably played an important role in the hunters social life. They may be records of myths about the first people who settled on the spot, or they may mark sacred places where special rituals took place, for example, the transition from child to adult. Previously it was thought that they had a hunting magic function.
The petroglyphs here was discovered in 1977 by high school student Trond Strømgren from Trondheim. They are located where it is the shortest route of the Trondheim Fjord from Fosenhalvøya to Byneset. This place may have been a meeting place for hunters from both sides of the fjord.
