History Mystery: A view of Walnut Street

This week's History Mystery is a postcard showing Walnut Street near 4th Street in downtown Des Moines.

Zoom in: The year was 1907 and Des Moines was in the middle of a population and development boom.

• On the left is the original Hotel Kirkwood at 400 Walnut St. The five-story building was destroyed in a 1929 fire.
• To the right is a mix of retailers, and it's where Capital Square currently stands.

Zoom out: Also in 1907, Des Moines started building its iconic river bridges at Walnut, Locust, Court and Grand Avenue.

Congratulations to Axios Des Moines reader Neal Westin for correctly guessing the street!
