Shanghai Postal Museum

This guide to the Shanghai Postal Museum opens with an engineering problem from the early 1920s: how do you raise a grand headquarters on ground that turns to soaked silt twice a day beside Suzhou Creek? You'll hear the unusual fix the engineers settled on, then follow the architects above ground as they went the opposite direction, building three stories of columns, a baroque clock tower, and statues of Hermes, Eros and Aphrodite over the entrance. The stamp galleries inside hold a few surprises of their own.
