There is only written documentation of Scythian and German subterranean dwellings. Remnants have been found in Switzerland, Meklenburg and southern Bavaria: "They had a round shape with a kettle-like widening at the bottom, from eleven to fifteen metres in diameter, and from two to four metres in depth".
In parts of rural Australia, subterranean houses are built in a manner similar to prairie dog holes. There is a "chimney" placed higher than ground-level and a lower, ground-level, entrance. This orientation causes a continuous breeze throughout the house, reducing or eliminating the need for air conditioning.
