This building was the only one that was preserved by the city after the Exposition ended. And get this--in 1897, when it was built, it was built of plaster, wood, and brick! And as you can imagine, it was deteriorating FAST.
In 1920, it was re-built but this time, thank goodness, in concrete. It took 5 years to complete the restoration of the building.
And if seeing this beautiful building wasn't enough, there is a bonus once you get inside.
But here is one more photo. I just love this photo.
