Tianjin is a major port city in northeastern China. Following the 1858 Treaties of Tianjin, several Western nations established concessions in Tianjin. The European-style houses, municipal buildings, and churches in Wudadao (Five Great Avenues) are legacies of that period. Standing, in contrast, are the city’s many modern skyscrapers, including the iconic 415m-tall Tianjin Radio and Television Tower.
