The Fort Cihou is a historic fortress in Cijin, Kaohsiung, and formerly guarded the northern entrance to Kaohsiung Harbor.
The fort played no part in the Chinese-French war, as the fighting in Taiwan took place around Keelung and during the blockade the French ships did not enter the port. During the Japanese era, the fortress was not used. After the Second World War, the hill was again strengthened by the Chinese army. Today it is a historic site for visitors.
