Chateau de Morès State Historic Site
An 1883 summer home anchors the story of an ambitious meatpacking venture and the town built around it.

Artwork inspired by Paul Barr
The 26-room Chateau preserves furnishings linked to Antoine and Medora de Vallombrosa, whose cattle, slaughterhouse, and refrigerated-shipping plans briefly reshaped the Little Missouri valley. The house makes wealth visible, but the venture depended on workers, transport, and contested land.
Take the house tour before the overlook so the landscape reads as infrastructure: rail line, river, grazing ground, town, and packing-plant site. The companion interpretive center supplies context the furnished rooms cannot.
Interior access is seasonal and guided. Floors, stairs, and original objects require a slower visit than the building’s modest exterior suggests. Tours and interior access are seasonal, so the grounds alone should not be assumed to represent the full visit.

Good to know
The furnished house makes wealth visible, but the de Morès experiment depended on workers, cattle, rail transport, refrigeration, and a packing plant spread across the valley.
