China’s treaty ports were cities along its coast and on major rivers which were forcibly opened to foreign trade by the Western powers, starting from the early 19th century. The treaty port era extended from then until 1943, and during this time foreigners had a significant presence in China. This new book contains more than 700 photographs of many buildings from this period, most of them commissioned by foreign interests. Many people argue that they should never have been built, let alone still be standing. But this book is not concerned with the rights and wrongs of how these buildings came to be. It simply celebrates their existence. A significant number are innately beautiful and all of them embody a history that has clear links to our own time and thus remain relevant.
