There are at least 5,507 historical markers in Maryland, by our count. We have cataloged 5,504 historical markers and 358 war memorials—each individually presented on 5,829 illustrated, annotated, and searchable pages of the Historical Marker Database. Pages for historical markers from this state make up 3.8% of our total. In addition, we are reasonably certain of another three historical markers in Maryland 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 Maryland marker in the database, Colony Of Maryland, was added November 9, 2005 while the database was being designed and tested (the Historical Marker Database went live January 1, 2006). It was photographed near Aberdeen in Harford County. The last one added was submitted on January 19, 2021, and titled Pocomoke City Historic Railroad Station. It is in Pocomoke City in Worcester County and had been erected in 1999. Keeping in mind that the erection date of many markers in the database is not known, one of the earliest historical markers we know of in Maryland was erected in 1792. More than one was erected that year. This one of them: Original Federal Boundary Stone, District of Columbia, Northeast 2, and one of our correspondents found it in Takoma Park in Montgomery County on September 11, 2016.

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.

Off the Beaten Path

You’ll find that even the smallest, least populated, or most rural areas of Maryland have been marked with history. Check out Wicomico County, Caroline County and Somerset County. We've only found, respectively, 67, 59, and 37 historical markers there. Visiting one or more of these parts of Maryland 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!
