Wiltja

Wiltjas are shelters made by the Pitjantjatjara, Yankunytjatjara and other Aboriginal Australian peoples.  They are temporary dwellings, and are abandoned and rebuilt rather than maintained.  Open and semi-circular, wiltjas are meant primarily as a defence against the heat of the sun, and are not an effective shelter from rain.
