Hours & Address

Please note that appointments are strongly encouraged for both the museum and research office. 

McConnell Mansion


Located in Moscow's historic neighborhood, the McConnell Mansion (at 110 South Adams Street) is an architectural and historic landmark. William J. McConnell, leading merchant, prominent Republican, and Idaho Governor from 1887 to 1893, built the house in 1886. On the main floor of the house are historic rooms interpreted in different time periods from 1900 to the 1930s. The second floor contains the restored master bedroom and exhibits, including hands-on activities for young visitors. During warm weather, visitors are invited to relax and enjoy refreshments in the backyard garden. The Museum Store carries books on local history, and notecards from area artists. Staffed by a corp of volunteers, the mansion is open for tours Tuesday through Friday, and some Saturdays from 1:00 p.m. to 4:00 p.m. Please call ahead to confirm hours.

Centennial Annex


The Centennial Annex (at 327 East Second Street) houses Latah County Historical Society's archival, photograph, and object collections, along with a small research library.  Our collections pertain to Latah County history and include materials donated by families, businesses, clubs and organizations, and local newspapers.  These robust collections are utilized by researchers pursuing a variety of projects, from filling in a family tree to figuring out who once lived in their home to writing a popular history book (see Timothy Egan's The Big Burn).  We invite you to stop by our office with your questions or simply your curiousity.  If you cannnot drop in, feel free to give us a call or send us an email. The Centennial Annex is open Tuesday through Friday from 9:00 a.m. to 4:00 p.m
