History of Beihai

After the 1876 Sino-British Treaty of Yantai, eight Western nations (the UK, US, Germany, Austria-Hungary, France, Italy, Portugal, and Belgium) set up consulates, hospitals, churches, schools, and maritime customs. Today, 15 of these western buildings remain in Beihai. It officially became an international tourist spot (旅游对外开放城市) in 1982.
