[3] Long houses are present across numerous regions and time periods in the archaeological record.
Outer walls were wattle and daub, sometimes alternating with split logs, with pitched, thatched roofs, supported by rows of poles, three across.
According to another view, the interior was divided in areas for sleeping, common life and a fenced enclosure at the back end for keeping animals.
Exceptionally, nearly 30 longhouses in a fortified settlement (dating to 4300 BC, i.e., Late Linear Pottery culture) were revealed by excavations at Oslonki in Poland.
Archaeological excavations have revealed extant timber postholes that delineate the support pieces of the original structure.
