During the Taisho and Showa periods when Japan occupied Taiwan, the "Su'nan Road" from Su'ao to Nanfang'ao was a branch of the "Su'hua Highway". This road was built along the bay of Su'ao and the side of a mountain. A few small hills were left on the roadside after its construction because the soil and rocks on the hills were thick. Because the small hills are good locations for overlooking the Su'ao Harbor, in 1985, the Su'ao Lions Club chose one of the bigger hills and, with funding from the Lions Club of Kitakyushu Higashi International, built a small lion monument park. Besides a pavilion and flower beds, a sitting lion was built on the hill using reinforced concrete. In 1994, the 'Yi Shan Road' to Su'ao Port opened, and the original 'Su'nan Road', the only road from Su'ao to Nanfang'ao, became a less traveled road. Nowadays, 'Su'nan Road' has become a popular walking trail for locals, and the 'Lion Park', sitting halfway up the mountain, looks down over the Pacific Ocean and is a good place to see Su'ao Port, Nanfang'ao Bridge, Nanfang'ao, and Beifang'ao. It is also a popular photography spot.
