It’s difficult to imagine what any city in the world looked like 100 years ago without the help of photos or maps, but the Taipei of 100 years past is an especially hard place to figure out.

These days, lots of people are thinking about Taipei as it was a century ago. That's because this year is the centenary of Taipei's official foundation. One of the most insightful exhibits about life in 1920's Taipei is going on now at city hall.
