Pán Gate

Straddling the outer moat in the southwest corner of the city, this stretch of the city wall has Sūzhōu's only remaining original coiled gate, Pán Gate, which dates from 1355. This overgrown gate, actually really a wall, straddles the canal and it's the only remaining land-and-water gate in China. The double-walled water gate was used for controlling waterways and has many defensive positions at the top. From the atmospheric gate, you can spy the exquisite arched Wúmén Bridge (Wúmén Qiáo) to the east and there are great views of the moat and the crumbling Ruìguāng Pagoda (瑞光塔; Ruìguāng Tǎ), constructed in 1004. The pagoda can be climbed. The gate is also connected to 300m of the ancient city wall which visitors can walk along.

To get there, take tourist bus Y5 from the train station or Changxu Lu.
