Culture

The houses of the Multnomah, like the other Chinookan peoples, were largely longhouses made of Western Redcedar planks. The size of a home depended on the wealth of the owner, with the larger houses furnishing living quarters for up to 100 people. Within each house, a particular family had a separate cubicle separated by woven mats that was approximately the size of a stall in a modern barn. Each family had its own fire, with the families also sharing a communal central fire in the household.
