National Register Sign Program

What is the Sign Program?

The Montana Historical Society's National Register property signs encourage locals and tourists to stop and learn about Montana's rich and colorful heritage, inspire others to seek Register listing, and promote historic preservation. If you own or represent a property that is listed in the National Register of Historic Places, the Montana Historical Society invites you to purchase a National Register sign. Signs cost from $35 to $62 each (see details below).

Each National Register sign includes a special logo and brief description of the property's historic significance. Since the program began in 1990, nearly 1,800 National Register signs have been placed across Montana. Montanans and visitors have come to recognize that a Montana National Register sign marks a place important to the history of our state. This is the only official sign program for the State of Montana and the only one that includes interpretive text detailing the history of your property.

All plaques are drilled for wall mounting. Post mounts are $7 extra. Applicants provide the threaded metal post. See installation instructions below.



The Process

After a property owner submits an application, Historical Society staff carefully craft each interpretive sign text, drawing from the site's National Register of Historic Places nomination and a variety of other primary and secondary resources. Each text is designed to highlight the property's distinctive history and pique the reader's interest. Applicants will receive a draft text for review and approval prior to preparation of final sign copy.

Applications are processed in order of receipt and on the basis of geographic distribution, so some time may elapse before applicants receive text for approval. After an owner approves the text and submits payment, signs are submitted to the manufacturer. Applicants can expect to receive their signs eight to ten weeks after final approval of the text.

Sending Photos

Property owners are encouraged to submit "then" and/or "now" photographs for publication in the Historic Montana website and app. Email jpeg files along with the full property address to or mail copies to Christine Brown, Montana Historical Society, PO Box 201201, Helena, MT 59620. Don't send originals. Copies will be returned. Email attachments larger than 10 MB will be blocked. You can also read and/or search most of the sign text by downloading the PDF file here (current through April 15, 2019).  



Mounting instructions can be found here.

Applicants are responsible for installing their signs outside, where the public can enjoy them, within a reasonable time of receiving their order. Owners or sponsoring organizations pay less than 10% of sign manufacturing costs. The Montana Historical Society pays for all other costs (including research/writing time) with its allocated portion of the Accommodations Tax.
