All of the Tor peoples are seminomadic, but villages are maintained as semipermanent residences and are the centers of social and religious life. Usually a village consists of eight to twelve houses built on piles, with a cult house in the center of the settlement. The houses are arranged in a straight line if located on rivers or ridge tops, or in a circle if in a forest clearing. In addition, branch villages, containing about four houses, are found all over the territory; these are used for Sexual intercourse (which is forbidden in the main village), as refuges from sorcery fears, and as temporary residences during sago processing.
