America's historic places, on the maps of their own eras

See the Wright brothers on an 1899 map of Ohio, Gettysburg as the mapmakers of 1863 drew it, and thousands more places pinned to the maps their stories came from. TreeAlive gives each one a permanent page: state historical markers with their inscriptions in full and their programs credited, and the listings of the National Register of Historic Places from all 50 states and the District of Columbia.

21,156 markers across 25 states, on more than 84,000 historical map sheets, beside 94,454 National Register listings. 25 state programs, credited on every page.

Every dot is a live page. Marker dots open that state's collection; National Register dots open the listing's own page.

For marker programs

These pages are built from each program's own published data, credit the program on every page, and keep marker links permanent: identifiers are never reassigned, so a code printed on a sign today resolves for good. Each state's page also carries print-ready QR artwork and road-trip tools that turn markers into destinations.

Run a historical marker program? Write to sam@treealive.com and tell us about it. New programs come aboard through a conversation: your published data, your credit line, and what the build involves.

Also on TreeAlive: the National Register of Historic Places, every listing on a map of its own era, and the heritage registers of Ireland, Wales, Northern Ireland and France, the official records of their listed buildings, protected monuments and archaeological sites.

Historical trails: several of these places in order, each stop on a map of its own era, with the drive at the end.
