## Caption

Did you know International Market Square is home to a piece of architectural history? 

Pictured here is our unique double helix stairway—believed to be one of the first of its kind in the United States. This design wasn't just for looks; it was built for efficiency. Two stairways spiral around each other so that arriving workers could go up one side while departing workers headed down the other without ever crossing paths.

Next time you’re in the building, take a moment to appreciate the "smooth transition" of the double helix.
