Penglai Pavilion, Fortified tower in Penglai, China.

Penglai Pavilion is a fortified tower complex at the northwest corner of the Shandong Peninsula where the Yellow Sea meets the Bohai Sea. The structure displays classical military fortification architecture with multiple buildings and walls that define the compound grounds.

Penglai Pavilion was first built in 1061, the sixth year of the Jiayou era of the Northern Song, on Danya Hill facing the sea in what is now Penglai District, Yantai. It is counted among the Four Great Towers of China alongside the Yellow Crane, Yueyang and Tengwang pavilions. The scenic area, made up of the pavilion, Tianhou Palace, Longwu Palace, Lüzu Hall, Sanqing Hall and Mituo Temple, covers 18,900 square metres.

The pavilion is the setting of the Eight Immortals legend: after drinking here, Lü Dongbin, Iron Crutch Li, Zhang Guolao, Han Zhongli, Cao Guojiu, He Xiangu, Lan Caihe and Han Xiangzi used their own talismans to cross the sea, giving rise to the saying "Eight Immortals cross the sea, each shows their power." The site also shares the name of Dengzhou's mirage with Leizhou's drum, Heyuan's mound and Guangde's burial as one of China's Four Wonders.

The complex covers 18,900 square metres on Danya Hill above the sea, so plan for stairs and slopes between the six main buildings: the pavilion, Tianhou Palace, Longwu Palace, Lüzu Hall, Sanqing Hall and Mituo Temple. The boundary between the Yellow Sea and the Bohai Sea is marked and visible from the site. Allow time to walk the whole grounds on foot.

Penglai's mirages, called the Dengzhou sea market, are ranked among China's "Four Wonders of the World" alongside the Leizhou drum exchange, the Guangde burials and the Qiantang River tide. The pavilion is also where the boundary between the Yellow Sea and the Bohai Sea can be made out from the grounds.
