The Four Gate Pagoda (Simen Ta) stands 15 kilometres south of Jinan's city center in the Liubu Hills, a small stone monument that is, against all expectation, the oldest surviving pagoda in China. Built in 611 CE, it sits in a landscape of wooded hills, carved rock faces, and scattered Tang-era stone sculptures that together form the Shentong Temple Heritage Site — a UNESCO-listed ensemble that most visitors to Jinan miss entirely.
The surrounding area contains the Dragon-and-Tiger Pagoda (a Tang-era twin-column structure), the Sima Chengzhen Hall with its rock carvings, and a substantial carved cliff face with Buddhist figures. The whole site takes about two hours to explore properly. Bus 50 from Jinan's center reaches the area in about an hour; a taxi takes 30 minutes. Worth every minute for anyone interested in early Chinese Buddhism and medieval stone carving.
