Historic Site & Archaeological Inventory
The Iowa Site Inventory contains information on more than 112,000 architectural, historical and National Register of Historic Places properties around the state. This information relates to only above-ground resources. Information in each file varies from a single photograph to a full National Register of Historic Places nomination.
The State Historic Preservation Office answers questions about individual buildings or creates standard reports for lists of properties by city, county or historic district. Reports can also be produced by builder, architect or architectural firm.
To provide information about a historic resource, please review the instructions, then fill out and submit the Iowa Site Inventory Form.
If you plan to submit digital photographs for survey and evaluation projects, please follow the instructions and guidelines. If you are providing images on a CD-R please include the Digital Photo Log.
Iowa Archaeological Site File
The Office of the State Archaeologist (OSA) maintains the Iowa Archaeological Site File, a master inventory of recorded archaeological sites in Iowa. Information is provided to the professional and vocational archaeological community, agencies and developers on a case by case basis.
The Guidelines for Archaeological Investigations in Iowa provide recommendations and guidance for conducting archaeological investigations throughout the State of Iowa.
