A walk around the Hai River area reveals some of the most interesting architecture in Tianjin. Britain and France were granted concessions in Tianjin after the Second Opium War (1856-1860) and established themselves beside the Hai River. During the late 19th century a number of other countries developed trade and concessions in Tianjin that resulted in distinct mix of European style architecture found in the area. In addition to the British and French concessions, there were Belgian, German, Italian, Austrian, Russian and Japanese concessions. Some of the most interesting buildings are located on Jiefangbei Lu, which runs parallel to the river.
