Iowa History & Heritage Guide 2026

The history of Iowa told through its places: sites worth the detour and the context they need.

Iowa has 6+ historical sites covered in this guide, led by Effigy Mounds National Monument, Herbert Hoover National Historic Site and Amana Colonies National Historic Landmark. Each entry below includes the practical details — what it costs, when to go, and how to plan around it.

Iowa is a heartland state of rolling prairies, covered bridges, and charming small cities anchored by a surprisingly vibrant Des Moines arts and food scene. Home to the world-famous Iowa State Fair, Grant Wood country, the Field of Dreams movie site, and the historic Amana Colonies, Iowa rewards visitors who look beyond the cornfields to find genuine Midwestern character.
