The walls and floors of the Minoan settlement of Gournia (Crete) have retained a perpendicular relationship since their construction between 3650 and 2025 BC. Their present orientation indicates that they were tilted in unison in an east‐south‐east direction. This was established by the reconstruction of a representative block, of which the side planes and the base plane were defined by the present orientation of the wall and floor remnants respectively. Stereographic projection methods, derived from geological practice, were used to determine the geometric elements and the orientation of the representative bl
