Tianjin has few actual sights, and it's the city's streetscapes, an assemblage of nineteenth- and early twentieth-century foreign architecture, mostly European, juxtaposed with the concrete and glass monoliths of wealthy contemporary China, which are its most engrossing attraction. The old city was strictly demarcated into national zones, and each section of the city centre has retained a hint of its old flavour. The area northwest of the main train station, on the west side of the Hai River, was the old Chinese city. Running from west to east along the north bank of the river were the Austrian, Italian, Russian and Belgian concessions, though most of the old buildings here have been destroyed. Unmistakable are the chateaux of the French concession, which now make up the downtown district just south of the river, and the haughty mansions the British built east of here. Farther east, but still south of the river, the architecture of an otherwise unremarkable district has a sprinkling of stern German constructions.
