About the Wisconsin Historic Preservation Database
The State Historic Preservation Office is the official state repository for collecting, managing and preserving information about historic buildings, archaeological sites, burial sites, and archaeological surveys in Wisconsin. We manage and make this information accessible online in the Wisconsin Historic Preservation Database (WHPD). Records are added and revised on a daily basis to ensure that your research is up to date.
WHPD gives users access to these four databases:
- Archaeological Report Inventory (ARI) – contains summaries of archaeological investigations at archaeological and burial sites.
- Archaeological Sites Inventory (ASI) – contains information about archaeological and burial sites, unmarked cemeteries, marked cemeteries and cultural sites.
- Architecture and History Inventory (AHI) – contains basic information on historic buildings, structures, and objects. Most records include exterior images.
- National Register of Historic Places (NR) – contains information for historic properties listed in the State and National Register of Historic Places including nomination PDFs.
There are three options, described below, for authorized researchers who would like to request access to the WHPD database. Please see our WHPD 2025 Policy memo regarding the price increase implemented April 1, 2025.
