led stone wall, tapering at the top and capped by stone slabs. They were mainly constructed by excavating a sloping trench about wide and deep, lining it with drystone walling as stated, which was
battered inwards and roofed with flat slabs; soil from excavation was heaped on top as at
Pendeen Vau or incorporated in the rampart of the enclosure as at
Halliggye Fogou, Trelowarren.

Function
It has been conjectured that they were made as refuges, or for religious purposes, or for food storage.
Fogous' central locations inside settlements and the work that evidently went into constructing them indicates their importance to the community, but their original purpose is no longer known. Many are oriented southwest–northeast, with the opening facing the prevailing wind.
Excavated examples at
Halliggye, Carn Euny, and
Boden suggest fogous may have been deliberately filled back in after use, or upon abandonment of the surrounding settlement.
Iron-age ritual use seems unlikely, given the Celtic druids' known custom of worship in outdoor spaces open to the sky.
Refuge hypothesis
Currently, both documentary and subsequent archaeological evidence support their use as refuges, possibly to survive raids, as first suggested by Kenneth MacGregor (2004).
Nancy Edwards wrote that "evidence would support this: Creeps, hidden chambers, and
sally ports, as well as the fact that most sonterrains were invisible above ground, would all have helped to provide protection in the case of sudden attack. They could, however, turn into death-traps if the aggression was prolonged."
Cold storage hypothesis
Although in their present damp condition, use for food storage seems impractical,

stated that Iron Age people in Britain stored their grain in "underground repositories", adding contemporary evidence to speculation that their main purpose was food storage.
Where they were open at both ends, a fogou could provide suitable conditions for storing some foods, especially the drying of meat, or storage of dairy products such as milk, butter, and cheese where natural moulds would assist in preservation of perishable foodstuffs.
Ashpits found at
Trewardreva and in the circular side-chamber at
Carn Euny were probably for preserving gulls' eggs, as was done on
Saint Kilda in Scotland. A layer of black greasy mould with charcoal, animal and bird bones at
Treveneague is also very suggestive of food storage.
Etymology
The word may be related to the Cornish words (plural ) and/or (plural ), both meaning "cave".
In the past, locals in Cornwall have called them "fuggy-holes" but this term is seldom used today.

History and archaeology

One function of the
souterrains of Gaul and early
medieval Ireland is to hide in boltholes to escape detection by raiders. Fogous may have had a similar function to the underground
kivas of the

Other underground structures such as "earth houses" or souterrains have some similarities with fogous. An example of an excavated souterrain is the site at Rosal,
Strathnaver, Sutherland. In this example no finds were made inside the structure and the roof may have been only partially covered with stones, a timber roof being present on part of it. It was suggested that souterrains could have been used as
barns.
[''Proceedings of the Society of Antiquaries of Scotland,'' 1967–68. Vol.100. Pps. 114–118] Fogous are often associated with dwellings such as

villages.
Petrospheres or "stone balls" have been found in
souterrains and, as possible symbols of power within prehistoric society, this discovery suggest a use other than basic storage of food and resources.
