Explore Maryland's Historic Markers

Historical markers have been a familiar sight on Maryland's roadways for more than half a century. Launched in 1933, the roadside historical marker program has proven an effective way to draw attention to the many events, people and places that have contributed to the richness of our state and nation. The marker program is administered by the Maryland Historical Trust in cooperation with the Maryland State Highway Administration. MHT reviews marker proposals, finalizes the wording, recommends general locations for placement and funds purchase of new markers. SHA determines the best siting, installs and maintains the markers, and funds replacement markers.
