We visited the building today thanks to Shorpy. It is just as interesting on the inside as the outside. The tall tower has an incredible sprial staircase running up the outside wall. The main lobby is excellent too. Up in the attic space is a long narrow runway with peep holes to the floor spaces below so that inspectors could keep watch on the employees as they worked behind the counters and in the sorting rooms! A major addition in 1930 on the back of the building doubled it's size and was done so well you can't tell where the original building leaves off and the addition starts. The museum is excellent and the staff are very friendly. Highly recommended if you are ever in the area!

There is much to admire about this old building. But, my favorites are the metal finials at the high points of the building. They are probably forged from copper.

I love the canvas awnings.

The post office left the building long ago. It is now known as the Castle Museum and is the home of the Saginaw Historical Society.

Can anyone make out the sign?

I was there a few years ago for a wedding but don't recall seeing the old post office. Here's a picture of it still going strong however!

I probably wouldn't have retired if I'd been working in that one. Not sure they would have gone for my spending my time making dioramas, though.
