A worldwide technology outage is causing disruption to some State of Illinois online systems. We are aware of this issue and are diligently working on restoration.

Welcome to the Historic Preservation Division

Historic Preservation is the collection, preservation, restoration, and interpretation of historic architecture, artifacts, and terrain of historical and cultural importance.

Research History

From students to family historians to professional researchers, everyone can learn something from the vast records and helpful online tools provided by the state. Look up an Illinois ancestor who served in the Civil War. Explore a timeline of Illinois history. Visit the Lincoln Presidential Library and examine rare documents.

Preserve History

The State Historic Preservation Office helps determine which Illinois buildings are listed on the National Register of Historic Places. Our staff reviews construction projects that might affect cultural resources and administer tax incentive programs for rehabilitation of historic buildings. Staff also can help communities turn their historic buildings into an economic asset.

Experience History

The state operates dozens of historic sites, museums, and monuments where visitors can learn the stories of Illinois. Experience life in a frontier fort. Walk the halls where Abraham Lincoln rose to greatness. See the remnants of a Native American city.
