Dolmen
Dolmen is a stone building which pillows a flat stone on a place which is combined with some stones, and the “Shisekibo” is a type of dolmen. Dolmen was not necessarily a tomb. Its distribution is wide, and we can see them in Asia and Europe after and B.C. In the Miyakojima Island, too, including the “Myaka”, there are some examples. There is a legend that it was handed down with a rice plant, but it is unknown. It is indicated that a “small shrine” is a Dolmen in the seabed of Tom Moya Reef in Kerama. Moreover, two stoneworks are checked on the island Mukaraku near the Tom Moya Reef.
