In 1967, the newly-formed Metropolitan Historical Commission of Nashville and Davidson County initiated a historical marker program to commemorate significant people, places, and events in the city’s past. Marker Number One, “Heaton’s Station,” was erected at Lock One road in 1968. The marker program is now one of the Historical Commission’s longest-running and most successful programs. By the end of 2019, 215 historical makers have been erected across the county. A map of the historical markers can be found on the Metro Open Data Portal.
