The old treaty-port concessions in Hankou are the largest surviving complex of European colonial architecture in central China, a half-mile-long bracelet of stone-faced banks, churches, consulates, and warehouses along Yanjiang Dadao and the side streets running back from the river. The British concession came first in 1861, followed by the French, Russian, German, and Japanese.
Highlights worth seeking out: the Hankou Customs House (1924) with its great clock tower, modelled on London's Big Ben; the former HSBC Building; the Catholic Cathedral of St Joseph; the gridded streets of Yantian He and Hong Kong Road. Most buildings are now used as banks, museums, or offices. Walk the area on a slow morning with a free hand for photographs.
