Introduction
Heping Island was called Sheliao Island in the past. It is located at the north of Taiwan. Heping Bridge connects the island to Keelung City. This is also one of the earliest places where Han people settled. Also, in earlier times, indigenous Ketagalan built their tribes here. In 1626, the Spanish army-built castles, churches and fortresses, preparing to do business with China and Japan. The castle on the southwest is called San Salvador, the saint savior. This is the first and currently the only castle in Keelung. During the Spanish occupation, Heping Island had busy trading activities with Southeast Asia. After World War II, the island was renamed Heping Island. Today, it is a famous tourist attraction.
 

Heping Island is perfect for diving. With years of erosion by the wind and sea, the eroded rocks and coasts have formed special shapes. The Keelung government has made Heping Island a coastal park with swimming pool, tour track, tourism service center and food and beverages.[1]
 
A big highlight of Heping Island Park is its sea-corrosion landscape. The park is full of sandstones. The strange rocks along its coastlines make a unique landscape after they are eroded by sea water and sea winds for a long time. Sea-erosion cliffs, sea-erosion platforms, sea-erosion ditches, and fatonis are all impressive, although the most outstanding might be the “mushroom rocks.” Other than the island’s geology, the body and trace fossils revealed by risen earth layers are Heping Island’s gems. To protect these precious resources, the rock zone is open at fixed hours and visitors must join a guided tour to explore it.[2]
