From Cataldo Mission — the oldest standing building in Idaho — to Craters of the Moon's volcanic landscape, Idaho's historic sites span fur trade outposts, Oregon Trail crossings, mining boomtowns, and engineering landmarks.
Idaho became a territory in 1863, shaped by fur trappers, Oregon Trail emigrants, Nez Perce and Shoshone nations, and the silver and gold rushes that drew miners into its mountains. The National Register preserves over sixty sites across the state. These ten span the breadth of Idaho's history — from the Jesuit mission built by Native American hands at Cataldo to the volcanic landscape of Craters of the Moon, from Boise's grand railroad depot to the remote homestead that may have sheltered Butch Cassidy.
The oldest surviving building in Idaho, the Mission of the Sacred Heart at Cataldo was completed in 1853 by Coeur d'Alene tribal members working under Jesuit guidance — without nails, using wooden pegs and wattle-and-daub walls. The Greek Revival facade is incongruous with its materials: a frontier mission built from local earth and faith.

The tower, visible from across the city, made the building as much a civic monument as a transit hub. When rail travel declined, the city bought and preserved it.

The Snake River Plain still holds active magma chambers. It was used as a training ground for Apollo astronauts before the moon landings.

The original adobe fort deteriorated after the fur trade collapsed; a full-scale replica was built in Pocatello in 1963 to mark the trading post that guided thousands of emigrants westward.

The mission sits on a bluff above the Coeur d'Alene River and remains an active pilgrimage site. Its survival across floods, mining booms, and a century of neglect is its own kind of historic record.

The downtown historic district preserves the commercial architecture from the 1890s through the 1930s — the built record of an agricultural town that outlasted the mining rushes by growing food instead of extracting ore.
View full record →Named for outlaw Butch Cassidy, who is reputed to have sheltered here in the remote Salmon River country while evading federal marshals. The ranch represents the isolated homestead culture of central Idaho — a landscape so vast that fugitives and settlers alike could disappear into it.

Hailey briefly had telephone service before New York City during its silver rush peak. The courthouse anchored a county that has reinvented itself from mining to skiing over the past century.
View full record →The American Falls Dam, completed in 1927 by the Bureau of Reclamation, submerged the original town of American Falls beneath its reservoir. Residents moved their houses and businesses uphill before the waters rose. The district preserves the infrastructure of a water system that made the upper Snake River Plain farmable.
