Statewide Inventories

The SHPO runs an ongoing statewide survey program that has recorded more than 50,000 historic structures and approximately 16,500 archaeological sites representing every county in Minnesota. This information, housed at the SHPO offices, is generated by the SHPO, other government agencies, county and local historical societies, educational institutions, research organizations, and private property owners.

These inventories contain Minnesota's known archaeological sites and historic standing structures. The majority of archaeological sites and many historic standing structures have not yet been inventoried; as that work is undertaken, additional properties will be added to SHPO files.

Standing Structures Inventory

This inventory of approximately 50,000 buildings, sites, structures, objects, and districts supplements the National Register of Historic Places database. Most properties included here have not been evaluated for nomination to the National Register.

More than 1,000 additional reports on Minnesota's standing structures are on file. Most were generated by federal agencies as part of the environmental review process; others are products of SHPO initiatives and community-based, grant-funded studies.

Archaeology Inventory

These 16,500 prehistoric and historic archaeological sites are described by type, function, time period, artifacts, general location, and setting. Most properties have not been evaluated for nomination to the National Register.

Most of the more than 4,000 archaeological reports on file are survey reports written as part of the environmental review process. Others are from grant-funded projects around the state.

Note: Access to some information about archaeological sites is restricted.
