Plaques & Markers

The Department of Archaeology and Historic Preservation (DAHP) encourages owners of historic properties to display plaques as a means of recognizing and promoting the State and National Register program, but plaques are neither a requirement of the National Park Service, or DAHP.  Due to budgetary constraints, plaques are not provided by the state at this time.  While the Department of Archaeology and Historic Preservation does not endorse any manufacturer of plaques, the following names and addresses of foundries are provided as a public service.  These companies are known as experienced producers of National Register plaques.

Note that many National Register plaques use the standard terminology of "This property has been placed on the National Register of Historic Places by the Department of the Interior".  Often this is supplemented by the historic name of the property and a built date as well as the date of listing.

There are no specific wording or guidelines for plaques or markers for Washington Heritage Register properties.   However if you chose to order a custom plaque we would recommend the following language: "This property has been placed on the Washington Heritage Register by the Governor's Advisory Council on Historic Preservation".

Highway Markers

Many communities have markers along the highway which denote the site of a Washington Heritage Register property or a National Register site. These are the infamous "brown signs" along state highways.

DAHP does not regulate these signs.  Requests to have a "brown" historic attraction sign installed in your community should be through the Regional office of State Department of Transportation (DOT).

The DOT office will only consider marking historic attractions if:

  • They are included in the Washington Heritage Register, as designated and maintained by the State Historic Preservation Officer; and
  • They have been approved by the Heritage Resource Center of the Washington State Historical Society; and
  • The attraction also includes one or more of the following features at the site:
    1.  An interpretive center and/or a guided tour
    2.  Visible historic buildings, features, or ruins with an interpretive marker

For further information about Highway Markers see the State Department of Transportation Traffic Manual, Chapter 2, pg 27-28 or call your regional DOT Office.

Heritage Barn Markers

When funding allows, barns that are added to the Washington State Heritage Barn Register receive a free 10" x 24" custom metal plaque.  The plaque, made by the Department of Corrections in Walla Walla, commorates the listing of the barn and allows for a form of public education by displaying the built date of each barn.

For further information about the Historic Register Programs contact Michael Houser, State Architectural Historian at (360) 586-3076 or
