The Massi della Vecchia are large rocks of sedimentary stone found in the territory of Giuggianello, a town in Salento. These boulders have particular shapes and are linked to a legend that tells of an old witch who turned anyone who didn't answer her questions into stone. Among the most famous boulders are the Letto della Vecchia, the Masso della Vecchia and the Piede di Ercole.
