The French Quarters - Commercial Streets
Tianjin prewar was divided into different zones for the British, French, Italian, Russian, Japanese, American, etc.
I spent most of my time exploring the French quarters as it was largest, most preserved and easiest to find. The restored area looked like a Hollywood film set.
The main buildings in the commercial sector are now occupied by banks. Do enter into the bank and appreciate the interior with high ceilings and stained glass windows. The security guards are on the lookout and so I did not bother to try to take the photos inside.
