Dugout (shelter)

A dugout or dug-out, also known as a pit-house, earth lodge, is a shelter for humans or domesticated animals and based on a hole or depression dug into the ground. Dugouts can be fully recessed into the earth, with a flat roof covered by ground, or dug into a hillside. They can also be semi-recessed, with a constructed wood or sod roof standing out. These structures are one of the most ancient types of human housing known to archeologists, and the same methods have evolved into modern "earth shelter" technology.

Dugouts may also be temporary shelters constructed as an aid to specific activities, e.g., concealment and protection during warfare or shelter while hunting.

First driven underground by enemies who invaded their country, the Berbers of Matmâta found underground homes the best defense against summer heat.

Burra in South Australia's Mid-North region was the site of the famous 'Monster Mine' (copper) and home to 4,400 people in 1851, 1,800 of whom were living in dugouts in the Burra Creek. Census data from 1851 shows that nearly 80 percent of the workers living in the dugouts were miners, with probably the majority being Cornish. Floods and the Victorian gold rush effectively ended the large scale use of dugouts in Burra, but people were still being 'washed' out of the creek in 1859.

Coober Pedy is a small outback town in northern South Australia, 846 kilometres north of Adelaide on the Stuart Highway, where opal mining is the dominant industry. Most residents live in caves excavated into the hillsides to avoid the harsh summer temperatures and work underground in mine shafts. White Cliffs, New South Wales is similar, in terms of climate, housing, and mining operations.

In north China, especially on the Loess Plateau, caves called yaodongs dug into hillsides have been the traditional dwellings from early times. The advantage of a yaodong over an ordinary house is that it needs little heating in winter and no cooling at all in summer. An estimated 40 million people in northern China live in a yaodong. Many people live in semi-recessed dugout houses in north-western China where hot summer and cold winters prevail.
