In the folklore of the Sámi, a Stállo (also Staaloe, Stalo or Northern Sami Stállu)[1] is a large, human-like creature who likes to eat people and who therefore is usually in some form of hostilities with a human.
On account of the identification of relics of ancient buildings with the 'stallo' in the southern part of the Sámi area of Sweden, archaeologists have come to refer to such relics as 'stallo sites [sv]' generally, following the lead of Ernst Manker's 1960 study Fångstgropar och stalotomter ('hunting pits and stallo sites').
Around sixty such sites are known, distributed along what is now the Norway-Sweden border, from Frostviken in Jämtland county to the south, to Devddesvuopmi in Troms to the north.
Scholars agree that these were temporary dwellings, probably for use in the warmer months, and that they reflect a change in the economic habits of their users, almost certainly associated with hunting or herding reindeer.
Nevertheless, there is extensive debate over whether the inhabitants were ethnically Norse or Sámi, where their permanent habitations were located, and their purpose.
