Fort Connah Site, Historical trading post in Mission Valley, Montana.

Fort Connah is a Hudson's Bay Company trading post from 1846 in Montana's Mission Valley, featuring an original central log building and reconstructed outbuildings around it. The site demonstrates how a European trading station was organized and operated in this region.

The Hudson's Bay Company established the fort in 1846 as a trading hub for the fur trade with local peoples. The company took several years to fully build and expand the facility.

The fort served as a meeting point for the fur trade between European merchants and Flathead Indians, where both groups exchanged goods and built trading relationships.

The site sits along U.S. Route 93 between St. Ignatius and Charlo with clear signage at the entrance. It is easy to locate and accessible for visitors wishing to explore the historic buildings and grounds.

The surviving building is a log structure, not stone: Neil McArthur began it in autumn 1846 and Angus McDonald finished it in 1847. It is believed to be the oldest standing building in Montana, and the fort stayed an important trading post until 1871.
