Traditions and folklore concerning giants, who were once alive and had supernatural powers, abound on Santorini. There are other stories about brave men or beautiful mermaids, as well as many beliefs concerning cutting down trees. The people of Santorini believe that a tree must never be cut down (even if it is growing on top of a church altar).
Other traditions concern sea demons, ghosts of the sea who were a true source of terror to sailors and fishermen.
Many of these old beliefs survive to this day. For example, ships that anchor in the port of Kameni tie their ropes in the shape of a cross to protect them from the “demon”.
