The hypogeum was excavated out of a limestone outcrop in the vegetable garden adjoining the parish church of Sennori. The multi-cell domus has 11 rooms which were interconnected at a later date.
The first and oldest nucleus is “T” shaped and has three rooms. The second one, accessed via a dromos (corridor), has a main cell from where different intermediate rooms open out. The extensive carved decoration with horn-shaped motifs is of particular significance. In one cell, referred to as the “Protomes Room”, these appear repeatedly three times over on a back wall, it too carved with relief architraves.
