弘治帝
In 1494, the Hongzhi Emperor (r. 1487–1505) of the Ming dynasty had a Yuanjing Temple () built for his wet nurse, Lady Luo, in front of Jar Hill (), which was later renamed Longevity Hill. The temple fell into disrepair over the years and was abandoned, and the area around the hill became lush with vegetation. The Zhengde Emperor (r. 1505–21), who succeeded the Hongzhi Emperor, built a palace on the banks of the Western Lake and turned the area into an imperial garden. He renamed Jar Hill to "Golden Hill" () and named the lake "Golden Sea" (). Both the Zhengde Emperor and the Wanli Emperor (r. 1572–1620) enjoyed taking boat rides on the lake. During the reign of the Tianqi Emperor (r. 1620–27), the court eunuch Wei Zhongxian took the imperial garden as his personal property.
