Shoushan is a mountain in Gushan District, Kaohsiung, Taiwan, north of the main entrance to Kaohsiung Harbor. It was named Ape Hill by the Dutch in the 17th century to describe many Formosan rock macaques on this mountain. It is also called Chaishan and includes the Snake Hill in its northern part, and Long Life Hill – named by Japanese in 1911-1915 for the crown-prince Hirohito – in the southern part. In some old maps, the peak of the hill is called Saracen's Head.
