The dolmen of the Gudina riverside Nature · Doñinos de Ledesma, Tierra de Ledesma, Salamanca Image of Doñinos de Ledesma, not of the place itself. In the annexed village of Zafrón a dolmen is preserved beside the bank of the Gudina, and another, that of Carrasco Zapata, at the spot known as Tozas; both attest to the megalithic settlement of a municipal district that today brings together barely sixty households and four deserted places.
