The Xinjiang Bridge straddles the most interesting sections of Ningbo and serves as an useful tool for finding your way around the city. On the eastern bank is the Old Bund or Laowaitan area - already popular with visitors by day, the quarter transforms into the city's major nightlife happening area after sundown. Stretching from the Catholic Church are old warehouses that have been transformed into riverside bars and restaurants and behind them are modern skyscrapers that complete the business district. On the other side of the river are the Town Hall and the Drum Tower where the architecture remaining from China's imperial times provides visitors with an excursus into the city's glorious past. Further south lies the scenic Moon Lake (Yuehu), Tianyi Square (perhaps the city's busiest commercial hub) and the Tianfeng Pagoda, dating back to the 7th century Tang Dynasty.
