Domus de Janas

Domus de Janas (Sardinian for 'House of the Fairies' or, alternatively, 'House of Witches') are a type of pre-Nuragic rock-cut chamber tomb found in Sardinia.

Built mostly between 3400 and 2700 BC, they date to the late Neolithic, Chalcolithic and early Bronze Age, including the Bell Beaker period.

Many other domus de janas can be found throughout the island, with the exception of Gallura (where the deceased were usually buried in megalithic circles, such as that those of Li Muri).

[5] These false doors usually appear on the back wall of the main chamber, and are represented by horizontal and vertical frames and a projecting lintel.

According to archaeologist Giovanni Lilliu, they were buried under shells of molluscs; according to other theories, they were left outside the tomb, being put inside only after they had reduced to a skeleton.
