Friends who have seen the movie Batman with me at the old post office that witnessed American history will be very interested in the old post office in Chicago, because the section that the movie started robbing the bank was shot in this building, and I am a big fan of Batman, So this time I came to Chicago, my first stop was the old Chicago Post Office. The old Chicago Post Office is arguably Chicago's historic, landmark building, which used to be the largest and most important post office in Chicago. Unfortunately, with the development of the times, the history of the changes, the building is now idle, the old post office has witnessed the history of the changes, so even if you do not enter the interior of the post office, you can feel the history of the heavy look only at its appearance! The old post office has a history museum of its own, there are many post office previous text introductions and exhibits, the museum is free to open, but it should be noted that the museum is not allowed to take pictures. Overall, the old Chicago Post Office is suitable for taking pictures and punching in, and it does not take too much time to visit. Address: 433 W Harrison St, Chicago, IL Opening hours: Open all day transportation: Take bus 125 to Canal & Van Buren Station and get off, 5 minutes walk.
