The quadrangular structure is a symbol of definition and delimitation, an enclosure and a code of conceptual order, a figure of the earth, of stillness, of the isolated instant, of immanence. It brings together the characteristics of a regular figure with perpendicularity and, being the simplest modular structure, through its nine nodes it can be fragmented into similar shapes with infinite progressions, found in the numerous “tributes” that many artists of every era and place have dedicated to this figure. The paving thus becomes the natural geometric extension of the Shrine and a visual hinge for the paths that converge from all main directions. Its square form restores formal dignity to a space with undefined edges and weak connections to the surrounding context. Within this square, 8,047 stones are placed—one for each Italian municipality—assembled according to a geometric pattern of triangular decomposition of the square form, referring to stone decorations created using the ancient opus sectile technique, reinterpreted in the early 20th century by the Bauhaus school in painting and textile works, particularly in the work of Anni Albers.
