Welcome to the Department of Archaeology and Historic Preservation's website! On this site you will find information on historic buildings, the archaeology of Washington State, how to navigate our regulatory processes and how to nominate properties to the State and National Register of Historic Places. Explore Washington State's historic places through our WISAARD Portal. And enjoy our image gallery!

The Department of Archaeology and Historic Preservation is Washington State's primary agency with knowledge and expertise in historic preservation. We advocate for the preservation of Washington's irreplaceable historic and cultural resources - significant buildings, structures, sites, objects and districts - as assets for the future. Please feel free to call (360) 586-3065 or drop by our office if you need assistance. The office is open Monday through Friday - 8:00am to 5:00pm. However, staff may be available at different hours than DAHP regular business hours. Please see the Meet the Staff page for each staff member's hours.
