【Designated by the City：Historic Site】Dolmen of Yonaha

It is considered to be a common grave of the Yonahabaru Clan who fled to Yonaha after being defeated by Meguromori in a battle at the shore of Harimizu in around 1365. It is a middle-sized Myaka with some signs of stonemasonry using axes and chisels. However, these are not technically as advanced as those in Sumurya Myaka in Kurima Island. The structure is 1.25 m in height, 2.7 m in width, and 2 m in length with a hollow inside. It is unknown when this was built.
