Beisi Pagoda, Buddhist pagoda in northern Suzhou, China.

Beisi Pagoda is an octagonal structure rising about 76 meters (250 feet) with nine stories, each featuring brick walls, stone railings, and wooden balconies that frame the exterior. The interior contains staircases connecting all levels and provides views across the surrounding cityscape from upper floors.

A pagoda stood here from the 3rd century, when Sun Quan built one in honour of his wet nurse; a Liang-dynasty pagoda followed in 532. The monk Dayuan directed the Southern Song design of 1131–1162, an octagonal nine-storey brick-and-wood tower. Fire destroyed it at the end of the Song, and the present structure was rebuilt under the Ming, with later repairs in 1960, 1975 and 2006.

The pagoda stands inside Bao'en Temple, which bears the title "first ancient monastery of Wu" (Wuzhong di yi gu cha). Its common name Beisi, "North Temple", comes from its position north of the old city centre on Renmin Road. The temple honours Sun Quan's wet nurse, the reason he founded a shrine here in the 3rd century.

You can climb the interior staircases to reach upper levels and experience views of both the old and new parts of the city. Wear sturdy shoes since the stairs are steep and narrow, which becomes more noticeable as you ascend higher in the structure.

During renovations in 1960 and 1975, workers uncovered hidden objects inside the metal steeple, including a copper turtle, Buddhist statues, and religious relics. These archaeological discoveries reveal that the structure served as a sacred repository for treasures across different centuries.
