A rock or stone is projected to us as solid and immortal. In particular, for prehistoric people who depended on the surrounding natural environment, their life and death were influenced by the surrounding environment and climate change. Therefore, the worship of giant trees or megaliths, which remain unchanging for a long time despite changes in the surrounding environment as well as humans, can be said to be spontaneous. At that time, people must have thought that Dolmens were a symbolic resting place for the spirits of the dead, protecting the living from harm they might cause. This can be seen as the burial items of Dolmens, such as ground stone swords and stone arrowheads, protecting the souls of the dead, and on the other hand, it also implies that the life enjoyed in this world guarantees its status and status in the afterlife.
