This impressive building is a reconstructed bark longhouse of the Seneca in the 17th century and is southeast of Rochester NY. Website here
The Longhouse is now furnished as closely as possible to an original 1670 longhouse, complete with replicas of European and colonial trade goods and items created and crafted by the Seneca. Also in the longhouse are crops, herbs, and medicines grown, harvested, and preserved by the Seneca who lived atop the hill at Ganondagan.
