There are at least 944 historical markers in Colorado, by our count. We have cataloged 943 historical markers and 67 war memorials—each individually presented on 1,010 illustrated, annotated, and searchable pages of the Historical Marker Database. In addition, we are reasonably certain of another historical marker in Colorado that we don’t yet have, and instead show on our Want List. Our correspondents have been finding and adding hundreds of markers a month to the database from all over the world, so next time you visit this page you will probably find that the numbers here have changed.
The first Colorado marker in the database, University of Denver, was added November 6, 2007. It was photographed near Idaho Springs in Clear Creek County and was erected in 1996. The last one added was submitted on November 29, 2020, and titled Twentieth Air Force. It is in United States Air Force Academy in El Paso County. Keeping in mind that the erection date of many markers in the database is not known, the earliest historical marker we know of in Colorado was erected in 1906. It was this one: Zebulon Montgomery Pike, and one of our correspondents found it near Cascade in El Paso County on January 21, 2008.

History Colorado is currently in charge of the familiar wood and now the full color illustrated official historical markers found all over the state. You will also find official markers erected by the State Historical Society of Colorado, a predecessor. We have 148 of their markers in the database.
In addition, E Clampus Vitus—not government affiliated—also erected numerous historical markers in Colorado, and we have 161 of their Colorado markers in the database. Also, a number of counties have erected historical markers on their streets and roads and within their public areas, as have some cities and towns.
Then there are federal government agencies that put up historical markers, especially in national parks and other areas under their jurisdiction. And finally, there are the numerous public and private organizations and individuals that erect markers. Some do this as a continual endeavor, and others once in a while, to mark something, someone, or someplace they find important or interesting. When one of our correspondents comes across one that satisfies our criteria, we add it to the database.
You’ll find that even the smallest, least populated, or most rural areas of Colorado have been marked with history. Check out San Miguel County, Ouray County and Broomfield County. We've only found one historical marker in each. Visiting one or more of these parts of Colorado might make for a pleasant road trip, and maybe you’ll discover more historical markers while you’re there. If you do, perhaps you’ll take the time to photograph them and, when you get home, become an HMdb correspondent by adding them to the database. Happy Hunting!
