Located in Hengmen Bay in the east of Jimo, Tianheng Island has been listed as one of the 26 islands for experimental development. In the late Qin and early Han Dynasties, there were 500 warriors who were loyal to the Qi king named Tian Heng. 

 

When Liu Bang became the first Han emperor, they refused to surrender and committed suicide together on the island.  In its western part, there is a 2.5-meter-high gravestone for the 500 martyrs.  The epitaph on the monument records the heroic deeds of Tianheng and his 500 men.  田横岛
