In response to our recent Neighbor of the Week feature on Claudia Rodriguez, who set out to visit all 149 of Riverside’s Cultural Landmarks, an accomplishment she now proudly claims, several readers asked if there was a list of all local markers. Historical Marker Database (HMDB) is a free user-editable online resource cataloging over 100 registered historical sites within just 10 miles of Downtown Riverside.
Whether you're planning a Sunday drive or an exploratory expedition from your couch, the HMDB provides detailed information about each marker including its location, historical significance and often photographs.
Five Must-See Historical Markers in Riverside
The Parent Washington Navel Orange Tree
Possibly the most famous of our markers, where Arlington and Magnolia meet at one of the busiest intersections in town. Parent Washington Navel Orange Tree planted by Eliza Tibbets herself started the whole citrus industry in Riverside.
The Booker T. Washington and Frank A. Miller Tablet
The newest of the markers and the one that inspired this little guide. You can find it near the very top of Mt. Rubidoux; this marker commemorates the walk to the top by Booker T. Washington and Frank A. Miller.
Charles Montagu Dammers Marker
Wherever you find a successful agriculture industry, you also find experts on bugs. Charles Montagu Dammers bought a failing grove near Victoria Avenue and Mary Street. In the meantime he saved the grove and became an expert on insect taxonomy. A bench and a butterfly garden sit with his commemorative marker at the corner where his grove once stood.
War Dog Memorial
At the far end of Van Buren near the entrance of the March Field Air Museum is the War Dog Memorial marker and statue. The War Dog Monument pays tribute to canine veterans of the US military. More information on the War Dogs is available inside the museum.
De Anza Trail Marker
Near the Santa Ana River Trail in Anza Narrows Park is the marker identifying the De Anza Trail. Juan Bautista De Anza was one of the first Europeans to arrive in the area on his way to the Pacific Coast.

A lifelong rail traveler, Frank A. Miller witnessed the evolution of train travel firsthand. In 1934, just a year before his passing, he embarked on one last journey—aboard the sleek, high-speed M-10000, a glimpse into the future of locomotion.
In the 1920s, the Riverside Chamber of Commerce turned a simple citrus gift into a nationwide sensation, greeting train passengers with fresh oranges, music, and grand spectacle.
