Sun Yat Sen Memorial Park is located near the vent shaft of the Western Harbour Tunnel. The land was obtained from reclamation from the sea outside Sam Kok Mar Tou.

Dr Sun was forced out of Hong Kong by British colonial government under the pressure of the Qing Dynasty because of his leading role in Chinese revolution. Since then, many times on his way back to the mainland, he could only meet his friends and supporters aboard a boat at the present location of Sun Yat Sen Memorial Park. The park is named after Dr Sun as a result. It is also the first park in Hong Kong to name after Dr Sun to commemorate his contribution as the father of modern China.
